I have a 668 credit score from experian and transunion but no credit score through equifax for another month. I do have a car loan for 19,000.00 owe about 17,000 now. Would like to trade it in for an infinitie G35 coupe or another entry level luxury car with a better resale value. What is my best way to get approved for an car loan through Infiniti Financial Services? Or a luxury level dealership with a low interest rate? I have 3 credit cards that have very low balances. less that 25% of my limit is used and 2 credit cards with 0 balances. All of my accounts are less that 1 year old. What should I do?
