I just purchased (9-8-2005) a driver's side vent glass (1990 Allante) from Cadillacs Only...........for $250 OUCH! Believe it or not I shopped around quite a bit. I found other's offering the same glass for $350 to $600! I'm considering selling my car for parts, LOL. FYI Cadillacs Only is located in Chatsworth California and their phone number is 818 772 0707. I hope you can find something more reasonable. If you do I'd like to know.
