My children and I love the legocar very much!
Especially, I like the flap (the window on the roof) which goes up and won when braking or releasing the brake. It's cool that you made it possible to fumble around with the setup.
The sound of this car is great, as well!
You could have used recordings of your mouth/voice generating the sound. ;-p
However, I'm glad you gave it a real sound (i.e the sound of a real engine).
Thank you very much!
Do you think that you will find the time to do yet another legocar?
