Hey guys, an FYI. Someone took one off my car last year (passenger rear quarter trim panel). Went to wrecker, no luck. Went to GM dealer... "Great news, the warehouse has 4 of 'em.... bad news is they are $840." After I got up off the floor I went and called insurance company. 2 days later I had my new panel on for a total sum of $908 incl taxes and install labour.
They are worth their weight in gold!!!!! Keep them or at least sell them to someone who need them.
