*sigh* Ok, did your brother actually have someone check the car in the metal? Or did he just buy it by going off the pics and the auction sheet?
If he bought it in the last day or two, let me know all the details of the car it was and I will try and track down the sheet for it. But you need to do it ASAP, PM me the details if you prefer. I sincerely hope he had someone take a good look at it, someone who understands the quality of cars required for compliance under SEVS in Australia. Lucky you asked before it was sent to Australia, or you could end up with a car that gets rejected by the compliance workshop.
In some circumstances, R graded cars are ok - panels can be removed for all kinds of reasons, not just for accidents - but if the auction sheet notes more than one panel replaced, or any kind of structural damage, you're gonna be pushing sh*t uphill to get it complied, unless the repairs have been immaculately done, and decent panel beating seems to be a very rare thing in Japan.
