The most comfortable and luxurious sports car I have ever

The most comfortable and luxurious sports car I have ever owned. I have has Porche's, Z cars, and B'mers but love this the most. Just fun and easy to go cruising in. Pure class! Added bonus...I can get a back massage as I drive. Oh yeah, it parallel parks itself.

grown to love it over the years

Purchased the car new Oct 2017 ( 2018 SL550 ) . I traded in a 2012 Corvette ZR1 . PROS- very good build materials and quality construction , almost constructed of all aluminum , good engine ( good sound and performance ) , the retractable hard top ( great in warm and cool weather -large glass sunroof ) , good fit and finish all around , audio and back up camera both good quality , wife loves the car , nice treatment at MB of Smithtown LI NY , very comfortable ride and interior , nothing has gone wrong with the car since purchase . CONS- initial price a little high ( 125K ) , yearly service too high , handling could be a little better , the looks took a while to grow on me . The car has 6000 gentle miles on it , is very nice to drive if you are taking a relaxing cruise . It handles pretty well if not pushed too hard . If you stay within the limits of the car the turns feel good , you just won't be going all that fast . I have other cars that handle better , but I do enjoy this car a lot . In the right weather I always come home with a big smile on my face . Did not really love the looks initially but they have grown on me over the years . Overall , I like the car a lot and will not sell it (ever) . I guess that's as positive a review as you can give. Hope this is helpful
