The reason I am tempted to say that it doesn't matter is that the Treasury has realised
that there won't be a great benefit to UK manufacturing (as a vast
number of the cars that are bought within the scheme will have been
imported). The 4 billion euros the Germans are putting into their scheme will have real impact on German manufacturing - including the Tier 1s like Bosch etc. In the UK, the domestic economic benefit will likely be far, far lower...
On the other hand, the real point of the scheme - as the
Haymarket/Dennis coalition kept saying, for example when a Guild member
questioned them at the SMMT press conference - was to inject confidence
into a struggling market.
Surely the scheme will not achieve this...
