I knew that when I bought the 87 Caprice. 60,000 mile warranty. No problem whatsoever until 61,000 miles, then all the tin parts started to come apart. Those automotive engineers know their stuff, no question.
Must be a 305 chevy powered caprice.. My 307 olds powered 86 is at 214k and still runs strong.. looks like heck and I dejunked the smog crap off, but it runs great...
