2004 Mercedes-Benz C-Class C320 Rwd 4dr Sedan (3.2L 6cyl 5A)
Best feature that attracted me is the comfort. Sitting in the car is almost as enjoyable as my living room couch (makes all the difference sitting in LA traffic). However by now I can probably write a book about all my mechanical visits (cheapest one being $450) ranging from transmission to power steering pump to sensor malfunction. I'll never buy a Mercedes in the future due to reliability issues because I know it's just a matter of time before my next break-down. P.S. The car has 65K miles, I am the original owner and I take great care of it.
