In-house car finance is a type of financing offered by dealerships. It allows you to borrow money from the dealership to buy a car, and the loan is typically repaid over a period of time, such as two or three years. In-house car finance can be a good option if you don't have the best credit score, as dealerships are more likely to approve your loan than a bank or other lender. However, it's important to compare interest rates and terms before choosing in-house car finance, as you may end up paying more in interest than you would with another type of loan.
