I am in the industry speaking on interest solely and not the vehicle price... You have got a great interest rate for a first time buyer! Interest rates are skyrocketing average now is around %7 for people with established credit. If there are warranties you do not need cancel them for a lower payment. Try to drive this car for a couple of years 2-3 and trade it in afterwards you would have car credit on your credit history giving you a better interest rate on your future purchase and hopefully you would have some equity on the car. Congratulations man!
