hey greg,
well i had the car advertised on carsales, gumtree, boostcruising, local pocket trader and about 4 different local facebook pages. the buyer told me that his mate showed him my advert on the local fb page. he has actually been wanting a V35 for about 12 months so he grabbed it pretty quick. to be honest i only got 2 inquiries from gumtree and 1 from carsales but a shit load of views and a fair few people had favourited or saved my ad.
hope that helps
