"With just over a week to go before the new 57 plates will be hitting our roads, many motorists will be searching garages up and down the country for their new cars.

"Before opting for the convenience of forecourt finance, it's worth checking out how this compares with other deals on the market. There are over 50 providers offering a range of unsecured loans and plenty of options available to borrowers. But with such a wide range of choice, comes a wide range of rates and deal types."
