BNPS.co.uk (01202 558833).Pic: Bonhams/BNPS..***Please Use Full Byline***..The 3.9 litre straight six might need a drop of oil...It may look like its run the gautlet with every Bond villain in movie history...but this classic Aston Martin would be worth a whopping £150,000 if restored to pristine condition. ..The 1966 DB6 Vantage was last purchased for only £4000 in the early seventies but sadly its owner locked it away in a very dusty barn in 1983 where the iconic motor has spent the last 30 years languishing under a thick layer of dust...Despite its rather tired appearance Bonhams are hoping to sell it for upwards of £30,000...and its first outing will be straight to the car wash...
