Well, its done. I just got my replacement Av from Reliable Chevy in Springfield, MO (shameless plug). I originally got my Red Z66 Feb. 28. Build date was 8/01 and had it in the shop 6 times in 3 weeks for an assortment of problems...some minor...some major. When I heard water running in the back and I was sure I hadn't ordered the kitchen sink...I had had enough. When I took it in to have the leak fixed and the rear gears replaced (again) there was a district big wig in the shop. After the dealer recommended a buy back...to my amazement he agreed. Well, 5 weeks later...new Red Z66. Only had to pay $547 (12.5 cents/mi) for the 4000 miles I used the truck. Then to my surprise...they are letting me use my GMCard again for another $1000! I do have a brother in law controller at the dealership which is probably the big reason why it went this well. Anyhoo...this is how a new rig should feel. My faith in GM is restored and I love this truck.
