If you're preparing to buy a new (new to you, at least) vehicle and you're wondering how you're going to pay for it, a little preparation will serve you well. If all you do is ask the dealer to arrange financing for you, you're not likely to get a great interest rate on your loan. If you shop around, though, you'll be surprised at the range of rates available to you. Your bank, credit union, or other local banks can offer loans, as can some car insurance providers such as State Farm. Your local American Automobile Association (AAA) office may be able to help you out, too. And, of course, online is perhaps the easiest place to comparison-shop. Drop by our Rate Center for a list of some good rates.
Once you have a good rate, you might take it to your dealer and see whether he can beat it. He'll often be willing to do so. When I was buying a car, I found a great loan rate offered online and went ahead and got the paperwork for it. Assuming I'd use that loan, I took the paperwork in to the dealer when I was buying the car. The dealer looked it over and came back to me with a slightly better interest rate, so I ended up taking that better deal. Soon after, when I was at my insurance agent's office, making sure my new car was covered, she was ready with an even lower interest rate for my loan. Don't assume that your options are limited -- they're not!
