A review on the Mercedes GLK 350
Engine and service is extremely reliable and the interior is very comforting in color and style. My one complaint is that it seems as though the leather seats wear to easily.
accountCircle Camela Z
One of a kind compact SUV that is a joy.
It's a workhorse. Very little maintenance. Looks great and is impressive to look at. The only thing that has gone wrong is a wiper quit working. You can also use regular gas which is a nice plus. I am sad that this model has been discontinued. It really was the best small SUV ever.

Everything in the car, can be adjusted so that your always comfortable!
I have purchased a Mercedes Benz for 35 years, it is the dependable car l have ever owned. The customer service is excellent. I recommend it to everyone, especially women. I have been stranded on the highway during rush hour, it took the service person 25 minutes to get to me. Once there, he repaired my tire within fifteen minutes and l was on my way. The annual service, Mercedes Benz brings me a loaner to my home, then they take my car in service it and return my car to me. I have never had any down time due to my car, l love Mercedes Benz, l will never purchase anything else!

It has a sport car mode, a sunroof and heated seats plus a great turn radius.
The car has a lot of power. There are no blind spots. I like the radio. It has heated seats.

Riding in style, benz is the way.
This car has a lot of power and comfort. Its reliable and has all the amenities. Heated seats are great. The size of the car fits everyone very comfortable. It has plenty of room for extra luggage or groceries without getting in the way of passengers. It comes with an open sun roof, making it breezy in the summer without having to open any windows. It also has navigation, bluetooth and many more options that is standard in this vehicle. The look of the car is beautiful and the color black stands out. The standard rims are exceptional. This is a wonderful car to drive.

Safest Mercedes crossover.
Only problem is the headlights go out every couple months. However, this is the safest car I have ever been in. I have been in several near death accidents and the car and myself have survived without a scratch. The most comfortable and luxurious car. My next car will be a newer version of the glk.

Use of Mercedes and durability.
Car has been solid. Not as quiet as I would like. Rides smooth. Easy to operate. Have had no issues except airbags and front lights seem to last only a year. But I have been able to replace. Would recommend this car. Like all cars it does not hold value.

Fantastic smaller, luxury SUV.
Excellent vehicle, smooth ride, no maintenance issues (if you keep up with service milestones). Very comfortable, fuel efficient. Dislike the lack of compartment space. Great storage space, can easily fit and adjust a child's car seat. Excellent for moving cargo or comfortable transporting larger adults.

Haven't found the value for money on this one.
It has performed ok but service is expensive and it goes through a lot of tires. I also do not like that I must use mid to premium gas. Ordered direct from Germany and windshield came looking like they had been sandblasting near it.

Reliability is questionable
Way too many sensors. Goes into very dangerous limp mode no matter where you are. Make you hesitant to take on a long trip.

My lights keep going out and I am tired of changing them.
Too many electrical issues. Constantly have to change the bulbs. They go out far too often. I have had the front lights changed 4 times within the year. The only ones I do not have issues with are the lights on the heated mirrors. Not sure what’s going on.

One highlight of my vehicle is definitely the panoramic roof.
When getting into the glk its a very open space, its super spacious. I don't feel so claustrophobic as to if I was in a Toyota. While driving the car the ride feels very smooth as if the road was, never an uncomfortable ride. Not only does the bag seat have lots of space so does the trunk and it even has a cover!

Mercedes 2012 is a good car.
My car is really great but it is just getting a bit old. The seats are super worn out. It works perfectly though. It is very reliable but I have had it in the shop I think a little too much. The shift stick is on the wheel and it was confusing at first but I am used to it now. The acceleration is pretty good given the year it was made and the size. It has 4 cup holders. It does not have an aux cord suitable for any iPhones over the iPhone four. It does have a nice tech backup camera though.
