You probably already know... I find Japan has alot of great used aftermarket wheels that are being sold off fairly reasonable. I think those wheels are bought by upper class citizens who decided to buy new sets of wheels or they got rid of the car.
Last time I looked over there... I was drooling on all sorts of choices, but is really rare in USA. Too bad, I didn't buy anything... it was complicated to buy and get it shipped to USA. I ended up buying a set from Germany... boy was the shipping pricy! I think I paid $350 to ship a set of wheels to USA.
