You need to be at least 18 years old to apply for vehicle finance. This may seem a little unfair seeing as you can drive a car at 17, but it’s to do with finance regulations. You have to be 18 to sign a credit agreement, which is what vehicle finance is. It’s a legally binding contract that only an adult can enter into. Between the ages of 18 and probably about 21 it may be hard for you to get finance simply because you’ll have no credit history for the lenders to look at. Again, seems a little unfair, but looking at your credit history is one of the ways a lender decides who to lend to and how much to lend.
