It hasn't affected the used car prices at all, in fairness quite the opposite. The cars that were scrapped had little or no value at all. The whole "Scrappage Scheme" was a complete nightmare from the start last year, totally mis-managed by the government, without talking to the manafacturers.
What has resulted, is all the cheaper cars have been sold because the makers were not able to build cars in advance, which in turn has lead to massive lead times for new vehicles – currently 5 months for a new Polo, I know other manafacturers are in a similar situation with all their smaller cars.
It was also an absolute Paperwork nightmare, plus all documentation has to be held onto for a further 7 years, during which any dealer can be audited.
The cost was also hidden as the government only paid the dealers between £850 and £870 depending on the VAT rate, the rest came from the manafacturer and this will have been passed onto the dealer without a shadow of doubt.
We definately don't want it to come back.
