Well after many many years and never owning a brand new vehicle except for a lease I decided to order a new Yukon Denali. After reading many threads about ordering I guess let the waiting game begin, still need to understand this whole system of ordering a new GM vehicle. When I went to the dealer they had pre printed order sheets except for exterior/interior color. They had all the RPO's listed and stated this was the only way that GM would except the order. I guess this was they way to not select anything that would be on the restraint list, so will see what shakes out as this is all new for me.
