Can anyone explain to me what dealer allocations mean and how the process works? We ordered a white diamond cxl with dvd and navigation package, driver confidence package, luxury package, sunroof with skylight and 19" chrome wheels on February 8, 2008. We are also GMS pricing which means we get GM employee discount. The dealer will not give GMS pricing for one off of the lot. He says we have to order. So we did. Dealer called yesterday (2-25-08) to let me know that they had an allocation and our order was bumped because of the color and that there is a constraint on WDT. Any advice??? How do I know this won't keep happening?
