This is my 3rd convo and while the smallest this is the most enjoyable and rock solid. While biased others might rate the Z4 & A4 higher/better the SLK has plenty of power and an esoteric aura the others lack. Other MB drivers render a salute just like bikers, they know the feel! The hard top retracts and closes quickly and offers silence protection that soft tops can't match. This is a fun roadster!
