McLaren P1

What you're actually getting

A 1:8 McLaren P1 with a working seven-speed gearbox, paddle shifters and a V8 with pistons that actually move when you push it. The butterfly doors open. The suspension works. It's less a model than a small argument for engineering as a hobby.

Nearly four thousand pieces means this is not a Sunday afternoon — it's a week of evenings, and the good kind. Bags numbered into the twenties, a manual you'll want to keep, and at the end a hypercar the length of your forearm and a half that looks right from every angle. Clear the shelf before the last bag.
