The UK scrappage scheme has sold 35,000 extra cars since its introduction under two weeks ago, according to the government.This amounts to more than a tenth of the £300m allocated until March 2010.Car sales have suffered due to the global economic crisis and scrappage was announced in the April budget in a bid to boost the industry.The government said one in five orders in the first two weeks of the scheme were scrappage orders.Ministers said they were “very pleased” with the take-up, although the industry remained cautious.A spokesman for the Society of Motor Manufacturers and Traders said it was important not to get "too over-excited"."We’ve seen indications that some manufacturers have had a positive increase in orders and we are encouraged by what has been announced. But we would like to leave it a couple of months to see how things develop," said the spokesman.Business Secretary Lord Mandelson said: "The scrappage scheme has got off to a flying start. It has given car sales a major boost and offers consumers a great deal. "Even after two weeks the sales figures are impressive. As it operates on a first come, first served, basis and cannot last forever, consumers should get in sooner rather than later for these great deals."
