    One minor issue that was addressed and resolved.

    Great GT. Very comfortable. Excellent performance. Super good looking. Would buy again. Is the 3rd SL we've owned and, is likely, THE best one of all. Doesn't have that V8 sound but at $20K less in price, we'll accept that . . . in a heartbeat! I.e. 0-60 in 4.5 seconds and 107 MPH in the standing 1/4 mile is plenty quick enough!

    actually it's a 2017 with 9K miles

    great combination of luxury and sportiness. drives like a 2 seat sports car when top down, or a comfortable sedan with top up. great acceleration for a 6 cyl. pricey but well worth it. fills a unique niche with little competition.

    An amazing V6 Grand Tourer!

    Excellent performing V6. And I say this after having owned an AMG SLK, an SL500 and an SL550. This one handles better than any of those 3, is an excellent performer (albeit, of course, not quite as fast as the SL550) and don't be turned-off by Mercedes typical conservative performance stats. Road and Track's are far more accurate: "0-60 in 4.5 seconds; and 107MPH in the standing quarter." Then compare it cost-wise to the price of an SL550 identically equipped (V8 excepted) it's more than $18,000 less costly. All-in-all, an EASY and wise choice. Fine GT car!

    New 2018 SL450

    Very happy with the '17 to date refresh of the R231 SL series. The new front facial treatment is much more sleek and balanced that the original take from the 2013 entry. New 9 speed transmission is so smooth you think it is a one speed.

    2018 SL450 a Great GT Convertible

    Been shopping for a new SL on and off for 4 years, and the Cosmetic changes to nose in '17 completed my looking into buying (would have bought in '17 but my 25 year old classic too a while to sell). Great performance, balance, appointments and safety wrapped into a fun and beautiful coupe/hardtop/convertible. Pricey, but top end of the Mercedes line is, as this well equipped SL costs over $100K. Mercedes tag line "Best or nothing" does drive the price, and caused me to part with the money. Very advanced vehicle, and a fun way to get on the road for a drive up the Coast.

    Great roadster with a comfortable ride

    Having looked at several sports cars, i decided on the 450 sl because of its comfort on long road trips as well as being a hardtop/convertible. It handles well , has descent luggage space and good looks
