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.
