I recently bought a 2007 DTS with 47,000 miles in great condition, except the beige carpet is horribly stained/dirty. Previous owners must have enjoyed hot chocolate, or something similar,but managed to pour several gallons on the carpet over the years. Cleaning has barely dented the issue. Anyway, no one seems to offer a complete replacement carpet for the DTS. Since the DTS is a derivative (I think) of the DeVille, will a later model DeVille carpet fit?
