anyone use the 750 off for hyundai financing, then payoff or switch loans at the 3 or 4 month mark? Is it basically "free money" or is there a catch? I noticed they are offering 0.0% financing on "some" elantra models, but not the sport. I'll be closing my deal on friday, I'll take the extra 750 off, if there are no strings. Wished they offered the 0.0% on the sport, that's a better deal in the long run.
