Everyone's having a cry about the prices but everyone knows that say...
R32 GTR-trashed and high km 15k, good condition=20k
R33 GTR-trashed or stock with somewhat high km's=20k, good condition etc vspec=25,28+
R34 GTR- trashed high km's=40k, good condition at least 50k.
If you really need the car sold as u say, go to car sales, set the price to 48k, and negotiations wont go below 45.
P.S: sexy car, what possessed you to buy 2 !
