Worst comparison. XU1 where not mass produced, they are a dime a dozen.
The only R32s worth decent money at the moment are the N1, nismo models and the AUS delivered ones.
This is nice and theoretically is worth your asking price, but I doubt others will pay that much for it. It is a buyers market atm and I think eventually If you stick to the price you will find the right buyer, just takes time.
