Chav accessories can knock hundreds of pounds off the value of a car.
Dog and smoke damage together with the effects of accidents could wipe as much as 15 per cent off vehicle values, research from used car company Network Q found.
But accessories installed by 'Chavs' - the much-derided new tasteless, poorly-educated underclass - can also reduce a car's value. Such "Chavtomisation", including Burberry-style seat covers, could cost a new owner up to £2,000 to put right, said Network Q.
