You get them out of the current mess, and move on. Find the middle ground between what they traded in, and new, say a 7-8 year old Corolla, and figure out how to get them in the thing without getting screwed again. Your claim that you stumbled on a "great" lease deal, that would be "fantastic" for your elderly parents is absurd. Unfortunately, a lot of elderly drivers have a bad habit of, at best, regularly bumping and bruising cars. When you rent (lease) a car, you return it is very good condition, or suffer the cost of repairing/ reconditioning it. The wife and I both had elderly drivers for parents, and both of their fairly new vehicles had thousands in damage when they ended their driving careers. Not only do you return the car in great condition, but what happens if, due to unforeseen events, their driving career ends next month? Now they are committed to a rental agreement for the next 2-3 years, for a car they can't use. That mess could easily cost them $8-10K to clean up. The next issue is that I seriously doubt that you would be able to qualify them for the super low lease rates, since it hinges on having great credit. Now you have to deal with gap insurance, since I doubt it is included in the low "teaser" rates. Without the added monthly payment of gap insurance, if they totaled the car, they would be on the hook for another coupe of grand. Sadly, I wouldn't invest to much in the alleged value of the Ford, based on the KBB number. That outfit is famous for giving inflated hope to sellers. The only way to learn the real value is to see what a few new and used car dealers are willing to pay for it, which may end up being thousands of dollars less.
