Id be really warey of anyone offering to do a swap.... offering to swap cars is mainly because they cant sell it in the first place!!! fair enough it is a V6 and most people are after TDI's nowadays so that might be why they havent sold it... but id still have my suspiciions!!!
V6 4 motion is very nice!!! and im sur eyou will get all the toys!!!
but id want to get theres full inspected... by a technician
