 I've owned my C230 Kompressor sedan for almost 7 years now and it's as fun to drive as ever.  I've got the six speed manual transmission, so the car is really responsive jetting around town, yet retains a smooth luxurious feel on the highway in the higher gears.  I haven't had any major repairs in 7 years, though the lock mechanism on the left rear door has just started to malfunction within the last month.  All in all a great car, that's been lots of fun to drive, at a very good value, if you consider I paid around $32K for it and drove it for almost seven years.
