I test drove the SLK 250 with sport package and 6 spd manual when it first arrived in Canada... they had to get it from MB headquarter coz none of the dealer ordered one for their lot
surprisingly, the shifting action for the manual gearbox is very very good...almost better than the 3 series!!!...and its not that slow if you keep the turbo in boost
however, didn't like the suspension even in sport mode and how big the car felt behind the wheel (felt like I was driving a E class coupe minus the rear seats)...not very nimble considering its a roadster, the C coupe has more sporting feel
the engine and 6 spd manual combo is top notch....if only they offer it in the C-class coupe... wishful thinking
