Hi all, I'm new to this forum but have been a part of r31skylineclub.com for a while now.. I have a nice loan under my belt to the tune of $20,000 and am looking at buying an R34 GTT. I know a fair bit about 31's, 32's and 33's but the 34 is fairly foreign to me. Could any of you tell me what I should look for in an R34 and where to go for a good deal (I'm in WA). Tim.
