if there ever was a sequel, would it be spoiled I mean there a video game and
if it went by it then we would know what was going to happen. and if they made a sequel that wasn’t the video
game, then the game dosen’t make sence. so I’m guessing no Cars 2 
i could be wrong though.
That’s not really true , because the game is done by THQ , not
pixar ( i believe so anyway ) . The video game is not from them , so therefore the video game isn’t true .
And they could also go and say the whole thing was a dream , just like the first race in the game .
Maybe they could have a little intro like the video game, but I imagine the story
being incredibly different. No one wants to see the same story twice.
