Cadillac DeVille 1985 to 2005 including:1985-1992
I am considering buying a 1991 Cadillac DeVille from a Friend. 131K Miles.
I hear noise in the exhaust and I am certain it is loose pieces in the catalytic converter. I called a muffler shop and they said it would cost anywhere from 1000 to 2000 dollars to replace. this seems high so...
