I have a 91 escort with abiut 160000 miles on it and it runs fine . Mainly because I took the time to learn about the fundamentals of repair work. I took about three semisters of classes on engine, trannie and body work. that way I could tell weather or not some mechanic is trying to mess me around. my svt has 70000 on it and I bought it with 45000. no problems so far.. good luck though.
