When i saw the title i just thought you wanted a mate v-mag, im gutted now. Anyway 250K is nothing nowadays, thats just over the average house in the uk so your not going to buy a whole warehouse and factory filled to the brim with stock and chinese people filling packets with parts. I reckon you could just about buy nortech for it though.
Are you thinking of buying one vinny or are you just looking at the moment?
I think tamiya could be part ex`d for your new B4 and some cash but you would have to fit a thrust race to it, they do actually do something you know its not just a fancy spacer
