Who Can Do Gm Warranty Work?

[Guest UVETTYA]

I got caught in the rain coming from work a week ago Saturday. Stupid me, I shouldn't have driven the Z that day. But, I did learn that both doors leak and water runs down the A-pillar and drips onto the floor board (and my leg). Both floor mats were wet.

I'm still under factory warranty for another 1000 miles, but I would rather take a beating than take the Z to the dealership for anything -- so I'm looking for a body shop that can do the work for me under my GM factory warranty.

Anyone?
