Something I've been wondering about since I bought my 2011 Nox, and I couldn't get an answer from the dealer. With my trade in, the money I had on my GM card, and talk of a $1500.00 dollar rebate I was going to pay the balance in cash. The day I went to close the deal I was told that in order to get the rebate I would have to finance it through Ally and make a minimum of three payments before I could pay it off. When I started to protest I was told that it didn't make any difference because it was a 0% interest loan. Their financial person said that if I wanted, I could take the loan for 36 months at 0%. I've been racking my brain trying to figure out why they would let someone do this.
