"I couldn't contain myself any longer. I had so much adrenaline, I just had to burn it off somehow. I figured running around the stage, jumping up and down," she explained.

Heil had big hugs for host Drew Carey. Then tried out her new $157,000 sports car.

"Who would expect a little girl from Tacoma winning a luxury automobile on The Price Is Right? It brought a lot of joy to my family and friends, and that's what means most to me," said Heil.
