I too think it slides forward. There is something like a guide rail on top of the nose. I did not bother too much about that because the project called for a "toy". However, as you might have guessed, I'm not so good at creating "toys", so the car became a little more complex. Basically only the canopy and the rear wheels remotely refer to the toy concept... Ah well, blame that to @Rhaven Blaack , he is constantly pushing me so I don't even try any more to hold me back when it is about "toys"..!
