Where should I take out a car loan?

So I want to buy a 2019 Honda Accord hybrid. I'm 27 years old and this will be my first time buying a car without my parents by my side (maybe I should have mom come?). My credit score is around 700 and I was just wondering where is the best place to take out a car loan. I bank with suntrust currently. My last car loan I took out with Santander for a $13500 car and ended up paying $26000 but I think it was bc my dad had to do-sign and he had bad credit. I don't want to run into this prob again if possible and I want to keep my payments no higher than $300.

Can anyone give me any tips? The car is $25000 and I plan to put down a $5000 down payment
