Vauxhall Belmont/Astra Belmont: Unbelievably, this ugly dinosaur has the dubious honour of being Britain's most stolen car. Thefts of this old-fashioned saloon totalled 436 in 2005 alone. Altogether now - why?????????

Why thieves like it: Even the newest Astra Belmont is now 16 years old, making the locks weaker than a 'Hollyoaks' storyline.

How to stop it being stolen: Don't bother. You'd be better off without this ancient piece of junk.
