The car I basically grew up in, an 85' Jeep Cherokee, is valid for this program and I've been kicking around ideas with my parents on how to take advantage of it.
Unfortunately they're working on selling one of their cars so they can retire, my car is serving me well, and my sister can't really afford a car payment at this time.
I'm still fantasizing about rebuilding that Jeep into an offroad crawler, but 4k off a new car is pretty sexy.
