Bit of a difficult one - there was a period about a year ago when good CR2s seemed to command quite high prices & got sold very quickly, now it seems the opposite is true... there was one on ebay that was advertised as 'as new condition', it had all the brass bits but was sold for just under £60!!

I have recently retired my CR2, but I am reluctant to advertise it for sale because I know I just won't get enough for it.. which is a real shame as it still is a very competent car (in its last race I finished 2nd in the A at a Silverstone Club meet). On this basis I would have thought that the same would be true of the PSI car (my car has a PSI 4-gear gearbox too

) - you maybe lucky and find that the novalty factor of this American conversion will attract a curious buyer but it might also put some people off?
