Minimum value $3500 - 4500, only if you have a qualifying auto, not all will qualify. My sons 99 Cavilier does not qualify cause its original rated MPG cannot be improved upon by the required amount. You also have to be buying something new and taking on that payment and full insurance, etc...and You had to have the car registered in your name for a minimum of 1 year before it qualifies for C4C...
