Most of the parts to keep you running arent dwindling out... actually they are parts from other GM products so they are still available. They cross to I think the 2500 truck for suspension, the engine is LQ series seen in many GM products, and alot of the other little pieces are from Saturns and so on (dont even get me started on that).
So unless you are looking for full blown body replacements......
I just bought roof lights and door handles from amazon.... took nothing to find
Hope this helps
