Beautiful car, with the top up (hardtop) or down. Very classic GT styling, not too brash..
Extremely powerful, close to 500 hp and loads of torque. Power comes on pretty smoothly, except when really "on it", when the supercharger shows it's stuff. Easy to control. Would like to have had the option of a nmanual transmission, though.
Awful! Big V-8 gets approximately 14 mpg, if I'm lucky!
Maintenance cost is fine, until the warranty expires, then every trip to the Dealer can get quite expensive. Especially for the "fancy" ABC/ESP suspension braking system that can cost a veritable fortune to repair. From what I've heard, M-B has done away with this system on the newer cars.
