There is one other way. Fly to either Atlantic City, or Las Vegas, and take a cashier's check for every cent that you've saved up for this build. Talk to the croupier and tell him
"I want to bet this on one cut of the deck, double or nothing, and a tie goes to the house." If you win, then you'll get the car that you wanted, and if you lose, well then it just wasn't meant to be.
