Like many, you likely had a poster of a Porsche on your bedroom wall. Well, ownership may no longer be just a fantasy. Here’s everything you need to know about buying a pre-owned Porsche.

So, you want to buy a used Porsche. Well, you have landed in the right spot for information. Porsche is legendary for its unwavering dedication to performance and impeccable quality. This passion for perfection shines through in the company’s cars and helps continue the mythos that there is, in fact, no substitute for a Porsche. This article covers everything you need to know about navigating the used Porsche market and how to get the best car for your money.

What Can I Expect to Pay for a 10-year-old Porsche?

A good budget for a 10-year-old Porsche is around $30,000. This amount gives you the opportunity to consider almost all the models Porsche produced at the time. Cayennes, Panameras, Boxsters, and Caymans can easily be found in this price range. However, the 911 is a different story.

If you’re interested in the more performance-oriented models, like the Turbo and GTS variants, they cost more coin. This is where the price starts to fluctuate with the model due to consumer demand and lower production numbers.

For a 10-year-old Cayenne, the price difference between the S model and Turbo is only a few thousand dollars. But for a Panamera, it is easily an extra $10,000.

The Porsche Boxster and Cayman do not have this price jump because the S model is as high as the trim level goes, unlike the rest of the Porsche range that offers a top-tier Turbo variant. 

Now on to the big one, the Porsche 911. For those not in the know, the used-911 market is extremely volatile. If I were writing this just a few years ago, I would tell you that you can buy a 997-generation 911 for $30,000 and it would be one of the best cars you have ever owned. While the latter is still true, unfortunately, the price is not. 

The prices of the Porsche 911 (997) from 10 years ago have almost doubled in just a few years. Today, it is hard to find a 997 of any trim level for less than $45,000. This is where the price jump is most noticeable. Highly sought-after Turbo models can range in price from $80,000 to well over $100,000.

What Do I Need to Know Before Buying a Porsche?

In your search for your new-to-you Porsche, there are a few things to look out for. The first thing you want to do is ask the seller for the service records. This paperwork is vital in ensuring that you do not end up with a Porsche-branded paperweight. Don’t get me wrong, Porsches are incredibly reliable vehicles, but they’re not all treated equally by their owners.

Porsche maintenance costs are expensive and some frugal owners may skip out on routine maintenance like brake fluid flushes; engine and cabin filters; or even oil changes. Neglect of this nature can wreak havoc on the internals of your engine, resulting in a lack of performance and fuel economy. 

A good way to spot a car that has not been well taken care of is to check out the state of its interior. Porsche builds its vehicles to an extremely high standard. So, if it looks like there has been a knife fight in the back seat, chances are the owner didn’t care about the vehicle very much.

Another thing you should look out for is the price. If the Porsche you’re looking to purchase is significantly lower in price than similar models in your area, this isn’t a great sign. Porsche enthusiasts tend to be very particular about their cars and know what they are worth. This is especially true of sports car owners and even more so if they own a 911.

Are Used Porsches Reliable?

Porsche is known around the world for its impeccable reliability, but…all machines have faults. The Porsche Cayenne and the Panamera share an engine, so they tend to have similar issues. Common components that fail are in the cooling system, things such as the water pump seal, coolant reservoir, and most of all, the coolant distribution pipe under the intake manifold. I spent many years as a Porsche technician and I saw these issues on a weekly basis.

Another common issue that comes up on Porsche’s family cars is misfiring. Spark plugs and ignition coils are maintenance items that should be changed at regular intervals. A lot of the time, they get overlooked by cost-conscious owners because they think shops are just trying to get more money out of them. This is yet another reason to get the service history, because the service intervals for the S models and Turbos are half of what they are for standard cars. 

When it comes to sports cars, the Porsche 911 is one of the most reliable sports cars that you can buy. Very few things actually fail on them. However, keeping up with the maintenance is key to ensuring the car and you live a long, happy life together. 

The Porsche Boxster and Cayman borrow their engine from the 911, but in a less powerful configuration. A recurring issue I came across in my time as a Porsche technician was oil separator failure. The oil separator is a black plastic box that sits on top of the engine and is a part of the vacuum system. This box is supposed to catch excess engine oil that is circulating in the system but, over time, wears out.

When the separator is going bad, you will see excessive gray smoke from the exhaust upon startup, or constantly if the problem is more severe. A little smoke on startup is normal because of the engine’s design, but if it continues after the car warms up, you have a problem. This should not be confused with white smoke. White smoke is a sign the engine is burning coolant, and that is a problem you should just walk away from where a used-Porsche is concerned.

Are Used Porsches Expensive to Maintain?

An easy mistake that first-time buyers often make is not factoring in the added cost of keeping your new pre-owned Porsche up to scuff. A low entry price tag is appealing but usually means the car has had many owners. And more than likely, the vehicle has not been equally loved by all of them. This is true of most luxury manufacturers, including BMW and the titan of German reliability, Mercedes-Benz.

Porsche maintenance costs are notoriously higher than other luxury brands due to their exclusive engineering and legendary build quality. In enthusiast circles, this added cost is known as the “Porsche Tax.” 

Depending on where you live and whether the shop is a dealership, independent, or a chain, the average per-hour labor rate for automotive work can vary wildly. For this example, let’s say it is around $80 per hour. This price is what your local neighborhood mechanic shop charges per hour to work on whatever comes through the door. I would not recommend taking your Porsche to these kinds of shops for service. Not that they’re not good mechanics, but because they likely do not have a Porsche or even a German car specialist on hand. 

The Porsche dealership is easily going to be double that amount per hour, but it has many different advantages that come with the added cost. Mainly for major repairs, the dealership can provide a loaner vehicle, and if anything goes wrong, they have a direct line to Porsche for solutions.   

For the most personal experience, consider an independent Porsche specialty shop. These businesses are generally privately owned by veteran technicians with years of experience. Shops like this often offer more opportunities for you to interact with the actual people working on your vehicle. A good independent shop can give you the feeling of dealing with actual people, not just a corporation trying to squeeze you for every dollar they can get.

5 Things to Know Before Buying a 10-year-old (or Older) Porsche

In conclusion, Porsche is a legendary automotive brand for a reason. Every model that the iconic automaker produces is built to a higher standard, and once you catch the Porsche bug, most people never look back. With all that being said, here are five things you need to remember when buying a used Porsche.

  • Always ask for service records. If the current owner does not have them, there are other ways you can get at least some information. A ton of records can be obtained by just getting the VIN number and calling Porsche. Also, tools like CarFax are helpful because most reputable shops use software that reports to them when services are performed.
  • Even if you have service records, always get the vehicle inspected by a Porsche specialist you trust before you buy. This is a good practice regardless of the manufacturer but especially for Porsche because of its exclusive nature. Seasoned Porsche technicians know what to look for and can save you thousands of dollars on repairs.
  • If the price of a Porsche you see for sale seems too good to be true, it most likely is. Porsche owners are a rare breed and tend to know what they have and what it is worth. So, remember, if the price is significantly lower than similar cars, proceed with caution. 
  • If the car checks out with your mechanic and the price is reasonable, don’t let higher mileage automatically disqualify your interest. Porsche sports cars are known around the world for their impeccable reliability. A testimonial to this is the fact that over 70% of 911s ever built are still on the road today.
  • The “Porsche Tax” is real. The average cost of a Porsche oil change is over $200 purely due to the volume and type of engine oil they need. Porsche is a luxury brand, so don’t expect any breaks on maintenance costs. The more performance-oriented they are, the more often they will need in-depth service.

Frequently Asked Questions

Apr 9, 2022

Are old Porsches reliable?

Porsche is known for being one of the most reliable sports car brands in the world. Their sensible German engineering has led to them making cars that stand up against the test of time. In general, they are one of the most reliable cars that you can buy if you are looking for something that is older and will not be a headache to repair.

Porsche has been making the 911 for well over 50 years now and in that time there has only been one major change. They went from air-cooled engines to water-cooled engines in 1998. Nearly every Porsche that has been released since 1998 is just an evolution of that water-cooled engine and should be reliable well over 150,000 miles.

Buying an older Porsche is usually a pretty safe bet. As long as you get the vehicle inspected and make sure that it is in good condition you should have no major problems. Porsche cars also have a very large enthusiast group that helps keep the values high so used models do not depreciate much.

What is the best second-hand Porsche to buy?

Choosing the right Porsche to buy second-hand is really up to your budget. Typically most Porsche vehicles are going to be a good option to go with if you want a used car you will just need to determine which one makes sense for you.

Typically the most affordable used Porsche will be something from their Boxster lineup. This is their entry-level sports car and they are a great driver's car if you want something sporty but do not want to spend a lot of money. They are known to be very reliable as well and hold up well over time.

The next car that I would recommend is a Cayman. These came along later but they have turned out to be a success for Porsche. They have similar styling to a Boxster but they have a more powerful engine. These are well-balanced cars that maintain value.

If your budget is higher, then I recommend looking at a used 911. These are Porsche's iconic sports car and depending on your budget I would consider one of the GT models since these are limited production and keep up with a lot of the supercars on the road these days.

Are old Porsches expensive to maintain?

Porsche vehicles are usually more expensive to maintain than most of the other American and Asian competition on the market. On average you should try to budget about $800 to $1,1000 per year in maintenance for a 911. The high cost of maintenance is not usually due to mechanical problems, but rather the high prices of labor and parts.

Porsche vehicles do use a lot of parts from Volkswagen Group so some parts are interchangeable, but all of the engines are used exclusively in Porsche vehicles. This leads to fewer parts being made which makes the parts more expensive. In general buying, a European luxury sports car is going to be expensive to maintain.

Porsche is considered to be a lot more reliable than a lot of the European competition. They will be cheaper to keep running than sports cars from Alfa, Ferrari, Lamborghini, and McLaren, for example. Typically Porsche maintenance costs are pretty similar to Mercedes.

2010 Porsche Cayman 987.2 version.
The performance is more than enough for the category of 2-seater sports coupons. Not the best car in a straight line, but a ton of fun on twisty roads. It has more space than you would imagine, with two trunk compartments. I have had issues with the shifter cables, infotainment unit, and clutch switch in my first year of ownership. Power seats, Bose, and navigation go a long way towards making the car feel newer than it is. 987.2’s have held value a lot better for their updated engines and cosmetics.

Rock solid 2003 Porsche 996.
Everything about my 2003, 996, C4S Porsche is perfect. IMS and RMS were fixed and we got a great deal on a low mileage Porsche. It's built like a tank and I've never witnessed nor seen better quality than a Porsche. Rock Solid and a blast to drive with the manual 6-speed. If you want to be flirted with, drive a Porsche.

Chronic Transfer case problems $6900- in repairs for my 2004 Cayenne
Both its transfer case module and transfer case itself and even servo motor goes bad. Interior is cheap and the worst part is the battery right under driver seat. Porsche forgot about the toxic fumes from the battery. And it's $1980- to have battery replaced by dealer. Not a single good thing about these models. They were made horribly defective with no responsibility by the makers.

Awesome, eye catching 2011 Cayenne S.
This car is a beast! Stylish as well as comfortable. Off road and hill assist are a couple of the features. Sunroof and awesome interior lighting. Gas mileage is comparable to other SUVs. Incredibly fun to drive. One issue is the car seems to have a mind of it is own and tends to change the settings. At times it will turn off the automatic lights and turn on the economy fuel.

The 2001 Boxster is an excellent example of a German engineered sports car.
My Boxster is a 2-seat roadster convertible. It has a flat 6-cylinder engine (base model). I purchased it because I wanted a Porsche and this has the perfect amount of power for where I drive (not too powerful with turbos, race car build, etc). The body styling is my absolute favorite. The firm handling is superior to anything else I've driven. No complaints.

2010 Porsche Cayenne a great family car!
Overall the Porsche Cayenne is a great family car, the leather interior holds up nicely to everyday normal use, even with kids, it is easy to clean and maintain. Just make sure to keep up with regular car maintenance since it is an imported vehicle if you are a do-it-yourself-er you will need to learn a different way to do things and buy extra tools.

200k miles and counting in my 2009 Cayenne.
My cayenne has almost 200k miles and runs great! It was purchased from the showroom and I am the only owner. Very little trouble with it! I would buy another one! Parts are expensive if they have to be replaced. Drives well in the snow and is efficient on gas mileage. My favorite feature is the heated seats. The vehicle also turns on a dime.

I use the vehicle to commute back and forth to work and for short distance trips. Overall, the performance, comfort, and look of the vehicle is awesome!

Not bad not great but the 2006 Boxster is worth it to me.
I hate that the motor in the passenger side window works on its own when it wants too. The spoiler stopped working. The sunroof (convertible top) motor went out. You have to be careful about how much oil you put in your vehicle and make sure you always use premium quality gas.

2008 Porsche Cayman is fun to drive, decent storage in hood and trunk.
