re: Scammed by auto dealership...What should I do?

Short answer = I don't think it was illegal, wrong but not illegal.

Also, if you plan to make a big deal about it to the dealership, I would not plan to have services performed there.

I never walk into a dealership without knowing what financing I can get elsewhere and I never tell the Finance Manager what I can get elsewhere. I simply tell him/her to give me your best rate.

The only way I would do 79 months on a vehicle is if I had other high interest debt that I wanted to tackle. 3.29 seems great for the loan term, which leaves me wondering what you could have got on a 60 month or less term.
