Noah thinks the standard-issue LEGO DeLorean is too big for the Marty McFly minifig. So he decided to custom-make a smaller DeLorean. It's only 4 x 10 studs big.
Great Scott! The doors open!
Can you see what part makes this DeLorean the one from BTTF1?
The tires fold downwards...
... using this mechanism...
Next, Noah plans to make a custom Marty McFly minifig. But right now, I'm asking him to clean up the Great Scott-ered mess of LEGOs on the floor. After all, my feet don't fold upwards to let me hover over those sharp bricks! ;p
Noah's age when he created this: 10 years, 10 months
