Really tight spot Aimless , I'm not sure what I'd do in your place. Probably it depends on whether the car is new or used. Were it a new car, I'd probably just buy them a used one to pass this winter, and let the new going back to the retailer. If it's a used one, then probably buying it so belongs to me, but I'd lend it to them until they can pay for it. Depending on how the take the "lesson" I might take possession of the car, but I wouldn't do nothing. Not sure, the background story makes a big difference.
