Not always a bad problem to have. I remember about 6 or 7 years ago I was in a pinch and needed a car asap as my girlfriend's Saturn blew a motor and my Subaru blew a turbo a week apart. I bought an old 2002 Subaru with 514,000 miles on it, from my boss for a couple hundred dollars, that had been sitting for a year or two. The head gaskets had been leaking for quite some time so the undercarriage had a nice coating of oil, but was rust free which is unheard of around here. It's got 585,000 miles on it now and still looks great underneath!
