Hiatt Pontiac GMC, 94th and Pacific Ave. I work there also, and the service manager is pretty cool about mods. He has referred customers to talk to me about adding mod to their trucks. What kind of problems are you having?
We do "cross-line" warranty work also. Chev, Buick, Olds, ETC. Would be happy to help you out if I can. No other local dealers I am aware of are fond of upgrades, but will let some slide. I work on light duty and medium duty both.
