Hey guys im wanting to purchase some Kameari GT seats i have been looking for a long time and it is the one thing i want more than my left testicle

I have been looking around and have finally found some on different places, ranging from expensive to more expensive haha..

Just curious if anyone has used yahoo japan auctions before... i have never used it to purchase good's but i do like to look through it, reason i ask is because the price difference is massive...
