I really envy you spending time with your daughter like that. That's pretty awesome! I'm sure she'll be more inclined to drive responsibly since she spent so much time building it instead of being given to her. Good job!
She backed it into a ditch the other week and got it stuck (no damage done). She was beyond upset. The older one hit 3 curbs and went through 2 tires and a few lower control arms on her Civic and it was a shoulder shrug "so what".... It makes a difference...
