LeapFrog Leapster game Cars

My son absolutely loves the movie Cars.  So when we got him his LeapFrog Leapster 2 we got him the game Cars.  Of the 3 games he has played so far I would have to say this is his favorite one.  This is helping him learn his letters and make words as he has to find the correct letters.  Whenever he wants to play his leapster he always asks for this game. I like how educational this game is.
