Grave Digger vs Traxxas

Every year when we go to monster jam in Vegas, Grayson and Chad love to watch the Traxxas cars. Chad really wants one, but due to his stinginess, he probably wont ever buy one. Grayson is obsessed. He talks about them all the time. He even got a Traxxas magazine and just sits and looks at it. He is nuts. Anyway, this weekend, my sister bought a hot wheels Grave Digger. I guess we will see what wins out: Grave Digger or Traxxas.
