Knew the car for all its life so bought it when it was being sold. I was mentally prepared to face issues but figured I'd treat myself to a Merc for a little while. Maybe because I was prepared, or maybe I was somewhat lucky, I didn't think the car gave me too much trouble - just enough to remind me that I bought it with 70K. For the 2 years and 20k miles I put on it, apart from the regular maintenance, I probably spent 1k, mass air flo sensors, brake pads and a couple of visits to check the 'check-engine-light'. For it's utility, saftey and the fact that it's a Mercedes, I have no regrets on owning it except maybe when I hit the gas stations lately.
