I had handed down to me from my father an 85 Accord HB (back in the day about 10 years ago) that he only drove 7 miles round trip to work. It had about 80K when I got it and since it had never been driven hard, everything broke on it once I got a hold of it. If you break in a car the right way, it'll last forever.

I'd be very skeptical about a granny-owned cream puff Mazda like this one.
