My mate sold his Megan cabrio to his girlfriend for £550 to add towards his purchase of a land rover discovery with a damaged gearbox priced at £670. The deal was done and the discovery was bought for £600 and repaired for an extra £500. My mate then taxed and insured the car to be legal on the road and used it. Shortly after this deal, my mate split up with this girlfriend but remained friends. 3 days ago he found out that she went behind his back and stole the logbook of the land rover discovery from his house flat and registered it in her name behind his back and reported to the car was stolen. She now claims that he got land rover discovery for her and now she wants him to come and get his Megan cabrio which she paid £550 for. My mate still has a copy of the ebay advert and hopefully the seller & myself as a witness to the purchase. My mate has called the police but they are treating this as a civil matter and donât want to get involved. The question is, what can he do.
