For me, buying a used car has always been a game of chance. Niky is right, there is no perfect engine and yes the first overhaul can come in the hundred thousands like in most Mercedes Benzes.

Even if I tagged along with me the best mechanic I know and gives me the thumbs-up to buy the car, there will always be at the back of my mind some doubt because we will never know the real state it is in until we actually get to drive it on a daily basis.
