Drawbacks of Your Guide to Auto Financing in the U.S.

Since this guide pulls together information from various sources, the final requirements—like documents, insurance, maximum term, and vehicle age/mileage—can differ from one lender to another, potentially dragging out the approval process.

And let’s not forget, comparing multiple offers takes some serious discipline: it’s all too easy to get caught up in just the monthly payment and miss the bigger picture of total cost and term, which could end up costing you more in the long run if you don’t stick to the guide’s advice.

How to Prepare Before Applying

Let’s break down the essentials of your credit score. Don’t just think about the car payment; remember to factor in insurance, fuel, maintenance, and taxes/registration to create a comfortable financial cushion.

And don’t forget about the down payment—putting down more upfront can lead to lower monthly payments and less interest in the long run, plus it helps you avoid falling into negative equity. It’s a good idea to use a calculator to experiment with different loan terms: if you want to save on interest, a shorter loan term might be the way to go. 

Compare your current APR with the new rate being offered, and don’t forget to include any opening or transfer fees in your calculations. Make sure to organize your documents—like your ID, proof of income, proof of residence, and an employer letter if needed. Lastly, do your homework on market values, including MSRP, used car prices, and Carfax/AutoCheck history, to make sure you’re not financing more than what the car is actually worth.
