My Ford Escort That Will Not Die

I own a Ford Escort that has 415,000. miles on the original engine. It just keeps going and going. One time a car hit us and the whole side of the car was dented, when the other vehicle backed away from my car the huge dent just popped out and it looked like nothing had happened to it. I thought it would be great to do a commercial to show that a ford can go 415,000 plus and in return we could get a new car for being a loyal customer. We have 5 kids and we cannot affor a new car and I don't know how much longer this one is going to last. Let me know what you think
