<prompt> Human: I bought a slightly used van for our family last weekend. It was 31k out the door, I paid 23k cash but had to finance the other 8k. The best financing I could find local credit union was 2.68 APR for 36 months. Last time I bought a car it was 1.49 for 48 months. So I said screw that, and I put the 8k on a credit card 2 cash back. Then I opened a new Citi card that offers 21 month 0 interest on balance transfers with a 5 transfer fee and I transferred the 8k over. My plan is to wait until the end of the 21 months and pay if off then. When you account for the 2 cash back, the total loan is costing me 3, or 240. By my calculations done after the fact, I would have paid 335 for that auto loan, so I saved 100. I thought it would have been more. Anyway, Im wondering... Are there are any unforeseen by me reasons this was a bad idea?  <response>: The best financing I could find local credit union was 2.68 APR for 36 months.
