People are not buying cars, fact. They are scared for their jobs.
If the Government gave a subsidy to all who choose to buy a car of say 10%, and up to £1000, then people may buy. E.g. buy a car for £3000, then the government would give £300, buy a car at £10,000 or more then the Government would give you £1000. It brings cost down for the consumer. It is the consumer that will save this country but we need a little back to do it.
