Key Car Loan Rules
- Lower APR = less interest paid over the life of the loan — even 1% matters a lot.
- Shorter term = higher monthly payment but far less total interest.
- Larger down payment = smaller loan = less interest charged.
- Get pre-approved at your credit union before visiting a dealership.
- Never negotiate the monthly payment — always negotiate the total price.
