Best car I have ever owned. It's solid, feels super safe. It' a fun drive! The trunk is deceiving. It fits more than you can imagine. Haven't had any problems with it other than a couple of minor things that were covered. It's almost 5 years old.

I have been fortunate through the years to own a lot of premium sports cars and the SL was not one of them or even on my "Top 5" list. This time around, my "wants" changed, with comfort, amenities and room as a top priority. Because of the new SL's aluminum construction and bi-turbo V8, it was added as a possibility. After driving everything else out there, I finally drove a new SL. It's agility, raw power and amenities were surprising, but the exterior lines seemed disjointed. UPDATE 11/2016 This car has not disappointed me in any way. It has been problem free, and its performance limits are beyond anything I had expected. I replaced the wheel and tire package with aftermarket 20" wheels and non run flat tires. I also added the factory rear spoiler. I hate run flat tires which come with the car, and the new wheels and spoiler give the car a more performance look. I have owned many nice cars in the past, but this car has definitely exceeded my expectations. I bought the SL, added custom wheels and the rear factory spoiler and I am very pleased. These additions seem minor, but they changed the entire look of the car and I am pleased.

My wife and I bought a 2015 550SL with every option except Magic Sky Roof. We are delighted with the car! The comfort for two persons, particularly on long drives is exceptional. All aspects of performance including acceleration, braking, and handling are well beyond a level anyone can use on public roads. Driving with the roof down on a winding road is an experience that every driver should have. We find it hard to imagine that any comparable car can provide as much luxury and performance as we are enjoying in our SL.

Replaced my Jaguar XK with a SL 400. Big step up in sophistication. Tech is far superior in the SL. Great rear drive handling. Mine has a CD player (Edmunds review says it shouldn’t). Also, the top is a two piece, not three, which limits the stylists in the size of the quarter windows. After eight months I remain very pleased with my SL. The shift points on the transmission are sometimes odd. Maybe Mercedes should consider providing ZF units as do many of their competitors. Still enjoying my SL. It recently required a repair to the retractable hardtop. It is a hydraulic system. It had a leak in one of the lines. A not inexpensive repair. Maybe a little early for that type of repair with only 34,000 miles. My last several months have been trouble-free motoring. My SL continues to turn heads especially when the top is down. I continue to enjoy my SL. I recently replaced the front sway bar links, an issue my mechanic had not seen before. Otherwise, no issues. I’m not sure that there’s a better looking two seater out there with the top down. My SL is great but not waterproof! Apparently not unique to my car. I will be applying a conditioner sold by Mercedes to the weather seals with the hope that I can stay dry while driving in the rain. My experience remains positive with maintenance and a few repairs. Brakes and tires were recently replaced with good service life experienced from both. Repairs have included a cam sensor which I'm told is not unusual for European cars and small leak of gas fumes which triggered a check engine light. The repair was to replace the fuel filter and a sealing ring.

I have owned a 2013 sl550 for about 6 weeks now. If you like a comfortable, good handling, fast car, look no further. Yeah, a 911 might be a better sport car, but this is a classy, sweet ride. Acceleration is awesome. With over 500 foot pounds of torque, it will make your ears flatten. Can’t tell you about repairing, haven’t had it long enough.
