Smoking in your car can knock £2,000 off its value

If you're one of the estimated 7.6 million smokers left in the UK, you ought to think twice before lighting up behind the wheel. Recent research by buying advice website Carbuyer.co.uk has found that a used car that's been smoked in could be worth up to £2,000 less than one that hasn't.

Carbuyer's survey of 6,000 people found that 87 per cent would refuse to buy a used car that's been smoked in. It's backed up by similar findings from automotive data expert cap-hpi, which estimates the lost value caused by potential stains, burns, and smells.
