Rsmore

I have a gt4 r34 sedan in factory manual i havnt been able to fine another one like it since buying it and its hard to put a price on a car u cant find another 1 of so my question is does anybody have one or has sold one recently btw mine no longer na and modified so is it really that rare i could only find build numbers on a unfamiler site and i dont know if they r accurate or not how do i find exact build numbers aswell? They are saying 3000 in gt four sedan manual produced ?
