Some people have no Heart
!
Like the others, I'm truly sorry for your troubles and the bad experience you are going thru.
My only suggestion would be...if there's no one who can help you here, (because of our smaller number) maybe you could post on th CF in a few days or so, where it will get some Nation attention and maybe catch the eye of those who can possibly assist you.
*A side note: Just Curious...If the car was used in a parade wouldn't it be considered a DEMO or maybe even Used?
Also, what was the mileage on it when you picked it up?
A further stretch....I'm not sure if the "Lemon Law" would be a avenue to explore, but maybe they could point you in the right direction.?
Good Luck,
