A Sainsbury's Finance survey found that the number of people who are planning to buy a car is at its lowest figure for at least six years.
The poll found that 5.14 million are planning to buy a new or used car in the next six months, 19% lower than the March-August 2009 total of 6.33 million who planned to make the purchase.
It is also the lowest six-month figure since the surveys began in March 2003.
Only 1.1 million people are planning to buy a new car in the next six months, a fall of 21% on the number a year ago.
The biggest increase in figures can be found in East Anglia where 11% more people than in the previous six months expected to buy a car.
Around 13% less people in West Midlands - the biggest drop - plan to purchase a car in the next six months than in the March-August 2009 period.
This is also the first time a six-month figure has dipped below £40 billion, with £39 billion expected to be spent on cars in the next six months.
Around 1.26 million people think they will spend more than £10,000 on a car. Another 467,000 said that over £21,000 in expenditure had been planned for their purchase.
