I found a used S4 with 142,000 miles on it. I don't know much about the reliability of these cars. Will a car with this many miles on it be prone to major problems? It is only a 1993, but it does have a lot of miles on it. Could any S4 owners out there or anyone who knows about S4's let me know what they think about the high mileage? Thanks in advance. Tom B.
