I had a kick of nostalgia to build something out of Lego, so I chose the 8070 Supercar kit.
It appears to be going out of production, as it's no longer sold by Lego and kits are being sold on eBay for double the original retail price. I got lucky and found a single kit on sale at Toys'R'Us.
It contains a motor to automatically raise/lower the scissor doors, reverse hood and rear spoiler. I (trivially) modified the gearing to both animate the pistons in the motor and drive the rear differential & wheels, while maintaining the above features. It also has functional steering.
This exercise also served as a reminder that properly applying stickers to LEGO is an impossible endeavour.
