Question by rococo: I was approved for a 72-month auto loan with simple interest at 9.9%...?
This is my first time financing a car and I seen a car at Carmax...the agent ran my credit report with Capital One, Wells Fargo, and Santander. The above loan quoted is with Santander. The car is a 2010 at $ 12,000. I plan to pay more than the monthly payment. I have a full-time job making $ 32,000 a year.

Is this a good idea or a bad idea? I have no mortgage and I rent an apartment. I haven't
