Am looking at a very nice $3500 1991 Cadillac Sedan Deville for a fun/drive a round town car. Anyone any idea what I can expect for MPG and potential problems. It has 95,000 one owner, well maintianed miles. Thanks

If you haven't already, post your question in the last-gen DeVille forum. I think it sounds like a good idea - if you're willing to spend a fair amount on upkeep as things break. If I were buying something of that vintage, I'd get an Allante.
