I'm looking to buy a new car?

I really don't understand your question.....did you not go to the dealer and pick your car, and meet with the finance manager? As a general rule, I like the credit union for car loans, generally better interest rates. What part aren't you sure of? Who the loan is through is not your only concern, but rather your interest rate, etc.....you could be getting hoodwinked and it could be legit. We need more information.
