Yes, Ebay or no, you are going to destroy the car. Reminds me of the Daffy Duck cartoon. "It's a great trick, but I can only do it once."
Why not just buy some rocket cars if thats what you want to play with? I think the idea of a nitro boost is to do it during the race when it's most adventageous. I'm not sure how you are going to light that wick (fuse?) when you are in the middle of a race and need that boost coming out of the last turn. And, if the intent is to just light it out of the hole, I again refer you to the afore mentioned rocket cars.
EDIT: Oh, and one little nit to pick. That quote in your signature. I've seen it before and it always gives me a little growl in the back of my head. I have an uncle who is developementally handicapped and I worked at a center that employed hundreds of PEOPLE with disabilities for 12 years. I've attended special olympics events and came away with a feeling of awe for the guts these PEOPLE have. I have more respect for them than I have for any "normal" functioning person I ever met. They don't lie, cheat, or JUDGE. They are what they are and don't hide behind masks or hidden agendas. Sorry, but that word that you toss about so freely and with glee is offensive to some of the more sensitive amoung us.
