Everyone who enjoys driving should have an SL

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.

Feels luxurious and sporty at same time. Steering in Comfort mode with a little too much assistance, but very good in Sport and Sport+ modes. Really enjoy driving this car. Have had the car for about 16 months and no problems. It is really fun, but still refined. Would definitely get this car again.

A classic Benz

Styling is subjective but I think it’s gorgeous. Twin turbo V-6 has plenty of power and gets 30+ mpg on highway. Love the massaging seats and other luxury features. Ride is firm, even in Comfort mode, but not punishing. I bought an off-lease car with 30k miles for less than half of list price. Like all Mercedes products, maintenance costs are high. This car has a very high “wow” factor.

Liked It So Much, We Bought It!

After owning/leasing 2 V8 SLs and 1 AMG SLK we stepped "down" to the new SL450 Twin Turbo V6. Not quite up to V8 performance levels but, surprisingly, close! According to Car & Driver's instrumented tests, and in contrast to Mercedes' typical conservative performance estimates, they say this car turns 0-60 in 4.5 seconds and breaks 107 MPH in the standing quarter mile. And, we don't doubt those stats for a minute! This car out handles our previous SLs and the AMG, and is amazingly close in virtually all other regards. We do miss the sound of the V8 engines, however, equipped with exactly the same options (the V8 excepted) our new 450 $tickered over $18,400 under the SL. And for that kind of savings, I'll sacrifice the V8 rumble for the nor-quite-as-exciting, V6 burbble. So far, we're delighted with our choice!

Ultimate everything

Having owned a SL550 and SL63 in the past, there is no comparison to the 2017 SL65. I saw this car in early 2016 while attending an AMG Driving School and it was parked in the Pit Garage and I though it the best looking car made by Mercedes. Problem, it was $235,000. Jump ahead to 2019 and I was able to purchase the same car for less than half the price new. With 18,000 miles and serviced regularly by Mercedes this car is exceptional. The vehicle looks brand new and runs with no problems detected. The ride is a tad stiff, but who cares when you step on the gas the back tires will smoke them if not careful. Extended warranties other than Mercedes are available and I would not own one without one. They are a rarity. The transmission is so smooth that you don't feel the up or down shift, but you can hear the engine pitch change or watch the AMG Instrument cluster as it reads out the gears as they change. Five star for sure.
