Vauxhall Nova: The Nova is best known as a favourite with the "boy-racers" who like to tart-up old bangers.

Why thieves like it: Flimsy security makes this an easy target. Also, because Nova's are cheap and their parts easy to come by, it has a loyal fan-base among young drivers. It's very easy to make one resemble the sporty SR model, so some are pinched simply for parts like alloy wheels.

How to stop it being stolen: If you've got alloy wheels fit locking wheel nuts.
