Alistair Darling has just finished prattling on with the budget as I write this, but he’s already confirmed that British car buyers will receive £2000 if they trade in a car aged 10 years or over for a new vehicle. It makes sense to us – which is why Autocar has been one of several magazines lobbying ministers for the deal.

Except, of course, that it’s not really two grand from the government. Instead, Gordon and his chums are only stumping up £1000; a similar amount will have to be contributed by the manufacturers themselves. Darling didn’t mention this during his budget speech; I guess it must have slipped his mind.
