Some 18 per cent of people planning to buy a second-hand car in the next six months will use a loan to finance the purchase.
According to research from Sainsbury's Bank, 5.35 million people plan on buying a used car between now and February 2008, spending on average £4,648 each.
This is an increase of £600 per purchase on the previous six months and a 12 per cent total increase, taking combined used car expenditure from £22.23 million to £24.87 million.
"Purchasers should remember to haggle when negotiating any car purchase to secure the best deal," said Steven Baillie from Sainsbury's Bank.
"Despite the fact that haggling can save the buyer hundreds or even thousands of pounds, many of us are reluctant to do this. Our findings reveal that around 50 per cent of people who are intending to buy a second-hand car in the next six months state they do not plan to haggle or will only haggle slightly."
A recent study from the AA found that demand for new and used cars is set to increase, with one in four people saying they plan to buy a vehicle this year compared to one in five in 2006.
