ah well if you're negociating for price that's a different matter. go in there and assasinate it. all cars have faults, find every one this one has and haggle it down. You're cop de grace will be it's cat D status, state how hard they are to sell, the financial climate etc, ask where it was repaired, do they pics of the damage, if you have an HPI check and it's had panel work done query the quality of the paint job etc, there's always something, and finally take cash, people can't resist cash. Good luck, hope you get it;-)
