I think the dealers were already offerring great discounts. The scrappage allowance plus their existing discounts would mean selling their cars at a loss.
I will soon have a friends Daewoo to work on. The job is to replace all locks and ignition key because the master key is not available due to joy riders keeping it when they abandoned the car. The insurance company won't pay out because the key was left in the ignition. They also won't insure it...
