I tried this powerhouse after driving BMW's for 10 years. More power than you will ever need (3 sets of tires in 18 months) but still an MB and not a BMW in drivability. Total brake failure (fluid drained out) in the first two weeks didn't help with impression but it was fine after that...no maintenance issues. Front fender is ripe for destruction on high parking bumpers. Traded recently for a winter car (S550 with 4Matic) but will go back to an S65 or BMW 7 series soon....
Seat needs the BMW alternating pressure pad treatment and accessories plug in should be easily usable
