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.
