Horrible. False advertising. I tried to purchase a small SUV from Star Jeep. Their website says they offer 0% APR + cash allowance for qualified customers.
My credit score is over 730 , I have a house and my credit card debt is less than 15% of total credit limit.
They wanted a co signer to get 0% and I provided them with my wife's info. Her credit score is over 760. They are offering 1.9% because we never had a car financed before. If we are not eligible for 0%, who is?
I wanted to report this dealership for over advertising on BBB and found out their BBB business review is already F on a scale of A+ to F.
