Definitely "shop around".
When I was looking to get financing for the gto my first choice was the bank I have a seven year always-positive relationship with and they gave me a stinky deal. So much for established relationships meaning anything with financial institutes.
So after going around to a few more banks I finally found a good deal with a bank that a friend of the family recommended.
