Putting in my 0.02 for Sangster Motors in Wenatchee, WA

They are a GM dealership, Pontiac, Buick, Olds and GMC trucks. We bought our '01 Montana from them.

No hassles or high pressure sales people, and a service dept. THAT EVEN I THINK IS COMPETENT!!!

I just don't know how to give a higher recommendation than that, as I do most of my own work and am a picky, perfectionist SOB that even gets upset at unnecessary tool marks.

Oh yeah, they sell all their GM performance parts at their wholesale price. They may not make any money on them but it sure brings in the traffic to their parts dept!
