Dealer said the same! – we can cancel and reorder, but would go to back of queue again. Not worth if for £250 – ordered 5-6 weeks ago. Arnold Clark – Vauxhall
Technically, both Motability and the dealership are correct according to the scheme rules. The AP is fixed at the time of order, regardless of any subsequent price movement.
However, if the AP does go down, some dealers, at their discretion, may cancel the Motability side of the order, then re-order at the new AP, leaving the manufacturer order still in place so you remain in the same place in the build queue. It takes the dealer about 5 minutes to do, but it is at their discretion.
You also have the option to cancel and go elsewhere to reorder at the new AP, but it would put you further back in the build queue.
It seems as though your dealership is rigidly affixed to the scheme rules!
