The Mercedes-AMG SL is a terrific convertible, with a soft top that rises and falls in a zippy 15 seconds, and at speeds up to 37mph. An SL hasn’t had a pair of rear jump seats for 2+2 seating like this since the much-loved 560SL of the late ’80s, not that any adult human is going to sit back there. Still, I can’t help but feel a mild twinge of disappointment at what might have – or perhaps could of, should have – been.
