Or 50kms every second weekend.. Unlikely, but then again so is the old mans genuine 22000km 1995 (first registerd june '96) 300ZX.
If he says he can prove it he probably can. It will be glaringly obvious the kms are non-genuine if he can't.
A little bit ironic seeing as i have no interest in the car, but dont the forum rules imply that if you are not interested in buying the car do not post in somebodies for sale thread?
Goodluck with the sale mate.
