Banks, dealerships, and credit unions offer car loans, but not under the same conditions. A good credit score will definitely help here. Credit unions will only process loans for their members. Whether it's a bank or one of the Dodge dealerships in Indianapolis like Fletcher Chrysler who ends up financing your car, the point is to work the numbers in your favor.
Once you've driven the car off the lot, make the most of it but don't forget your responsibilities as a car owner. The better you take care of it now, the higher you can sell it for in the future if you choose to.
