The allocation number will tell all Chevrolet dealers exactly how many trucks/suvs GM will build for them over next few months. Unfortunately, this does not constrain the dealership from pre-selling more than the earned allocation, as GM does not manage this process in any way. In other words, a dealer (knowing they only have two Denali’s arriving within the next six months) can pre-sell 20 and simply tell the customer that the order has been put in. For the 18 customers who are at the bottom of the list, they are at the mercy of whatever story the dealer tells them regarding the production of the vehicle. Dealers are under no obligation to disclose how many of their earned allocations are spoken for when making pre-order sales. As such, many dealers don’t disclose this information to the customer because if they did, you would probably walk right out the door.
