I needed to buy a piece for the intake on my Isuzu -09 at the dealer in Udon. They did not have it in stock. In fact they did not have any parts in stock. But they could order it if I paid a downpayment, about 30%.
In Europe if I needed something for my car or truck, I went to the dealer and bought it. Period. Unless it were a very rare part, they had it in stock. And if not, they ordered it without any demands for downpayment.
