1999 Mercedes-Benz SL-Class Reviews, Pricing & Specs
What owners say
"Owners of the 1999 Mercedes-Benz SL-Class generally love the car for its timeless design, smooth performance, and luxurious comfort. Many highlight the impressive power of the V8 engine and the quality materials used in its construction. However, some drivers express concerns about the rising costs associated with maintenance and repairs, as well as occasional issues with the brakes and speaker systems. Overall, it’s seen as a classic that provides a great driving experience, but potential buyers should be ready for upkeep."
This was one of the last cars designed by Bruno Sacco, one of the greatest automobile designers of all times
May 19, 2025I always wanted a SL500 and bought one 6 years ago. For the most part this car has been extremely reliable. I am a mechanic and maintain it very well and feel this is the most important thing no matter what kind of vehicle you own. About the only problems I have had with this car were a speaker going out and changing the strut supports which was a very inexpensive repair. The most expensive maintenance item was servicing the transmission, which was about $250 for fluid and parts. Mercedes used to have a "sealed transmission" which supposedly never needed to be serviced. After researching this I found out that many transmissions of this type ended up failing so I elected to service it and it is still trouble free.The gas mileage is surprising good as well, with mild mannered driving you can expect 23 to 25 MPG on the freeway. If you are thinking of buying a used SL make sure it has been serviced and taken care of. Buying a fixer upper SL is not a good idea. The parts and repairs can be very expensive.
November 23, 2012Design & styling is great, speed and handling are best features. Down side is repairs are becoming more frequent and costly. Just bought 4 tires, over $1k for them and the worst part is performance tires are only rated for 40-45k miles and I'm sure your aware, you don't get anywhere near that many miles from them. Doesn't matter, I love this car.

January 9, 2021I love this car...this is my second Mercedes SL and I would not want to own any other model or car. This car is in a class of its own. The car says it all. If you ever drive one, you won't rest until you own one. Thereafter, it is Mercedes forever. Love my car.
July 20, 2009Overall a great car, affordable now as a used car, great touring car that you can drive hours in and feel comfortable. Fit and finish are very high quality, timeless styling and with the right set of wheels is a real head turner. Mine came with a Panoramic glass hardtop from the factory, a highly desirable option.
July 27, 2014exceptional handling,steering,acceleration.Very quiet until you hit 6000 rpm,then it sounds like a symphony of power. Love the shifting options and the extra push buttons for handling,traction and sport driving. Looks as classy as the new ones.
February 22, 2010Best looking car on the road, big surprise, 24 mpg on trip to Florida, highway driving perfect, 14 hour trip, no discomfert at all, proformance great, only small complaint, brake noise and dust. Would buy one again tomorrow, great car.
November 13, 2009I have own several SLs over the years. 1991 through 2002 are great cars . 1999 through 2002 by far the best.
