Again another issue I have dealt with before... I have now owned the car for several years and am the first owner of the car in Australia, it has taken me to only recently to have the body work almost to the point of how I want it. I only stopped using the rims less than a year ago.The importer made me an offer to get the rims once he realized what they were, but I had way to much work to do on the car then to be able to try and guess what size/width/offset would suit my plans. As such I did not pay a premium for the rims, I paid for the car as a package of what it was in its entirity, this was more than some r34's and less than others depending on the specifics of each car... it was the best one that was within my budget range at the time! In essence it makes your point nute.
2k is still a little lower than I will let the rims go for, if I needed the cash it is an offer I would definatly consider. Good luck with your search, occassionally you can find some that someone doesn't realize what they have or needs gone and you can then get individuals or sets at a great price, but make sure you confirm stud pattern, height, width and offset otherwise you may end up being disappointed with the rims you get.
If I come across any being sold I will try and remember to PM you their details.
