i own a 96 deville wich has been nothing but great i love it but i have recently aquired a very nice 94 seville sts. i was wondering if anyone new if parts from these cars are interchangeable? besides the ones that obviously not...(rear end end body parts)

 

The deville and seville are built on the same platform, the sevilles is just shorter. You should be able to swap out wheels and hubs. Mabye some other suspension pieces. The engine should be almost the same, the majority of the parts initshould be interchangible. I am not that familiar with the seville, i wish i could tell you more, but these are the things im sure about.
