Best ever. Greatest overall car.
One of the best cars I have ever driven, has all the electronics I can have including their version of self drive. The fit and finish are above any standard and the handling is fantastic. Breaking is great as is the acceleration. Self parking is another great thing in the car.

Pros from Owners

likeFilled Richard L.

Plenty of style, power and prestige. Proud to own this vehicle and it is a dream car. Power seats, heated seats, hardtop convertible. Comfortable and fits my frame of 6: 2:. Great audio system. Outclasses all the vehicles in its price class.

Cons from Owners

dislikeFilled Richard L.

Haven't really experienced any problems. As with all Mercedes products, cost of maintenance is high. Difficult to find servicing dealers that are close to home. Requires a call to dealership for car pickup, servicing and return to my home. Dealer does not charge for this service.

Is The 2018 Mercedes-Benz SL-Class A Good Car?

I bought the 450SL and I love it. Reliability has been 100% and the ride and power are first class. Gas mileage is surprisingly good.

How Reliable Is The 2018 Mercedes-Benz SL-Class?

Knock on wood, no problems whatsoever. Took me a while to learn all the controls and options but watching the videos provided by the Mercedes dealership have helped.
Janet G.

Is The 2018 Mercedes-Benz SL-Class A Good Value?

Value I suppose is in the heart of the buyer. Drive away price was $103,000 including all options and tax.
