These cars are for people that in general do at least their own mechanical work. Or do not mind spending the money. Otherwise usually they will be very expensive to maintain. There will be some exceptions to the rule of course.

There was a guy interested in purchasing a 123d with over 500k or he purchased it. His first questions where along the lines of where is the best place to get it repaired.

Maybe I should have not said it might be better to pass on it if you use only paid for services. Can you imagine the bills if the car was pretty run out? Unless the previous owner was totally on top of everything.
