I got the MM back from my favorite GMC dealer this morning after having the new spec alignment done. Got a print-out of the new alignment. The tech nailed it all. He even said he now understands what they were trying to accomplish. New tires, so time will tell.
This GMC dealer (Premier in Rittman Ohio) is really home-town business. You can visit the guys in the shop with no problem. That is a rarity. I have known them for 25 years, and bought several cars from them. Only use them when I cannot do the work at my own repair shop.
