Your Credit Union!

If you're a member of a credit union, it will generally offer you the best deal. However, a loan is like any other "product", you should shop around. Contact your bank, and a couple of others as well, sometimes they will beat an offer to get your business. Also try LendingTree. Com. They wil get your at least 4 competing offers in about an hour.
credit unions usually give out lower interest rates but lately dealers have been having go deals on rates so you might want to check with them also.
Either will give you a good rate. If you apply at both places, they will likely compete with each other , within reason, to earn your business. Car financing can be at very low rates, but there is usually a higher dollar paid for the vehicle to begin with so the finance costs are already factored in to the price..
While usually a credit union will give its members a pretty good rate, you need to compare all of the offers. Also counter offer because dealers especially, will have multiple interest rates they can use. Be sure to check APR at top of sheet or their credit offer to compare, because some banks, dealers, etc. charge doc fees, other items that really are just additional finance charges on the loan. Compare apples to apples, make sure it's same amount, same term, etc. You have a pretty good score but not the highest level for getting a loan. You might try eloan.com, also.
Credit unions usually offer the lowest rates.
