Brickheist's take
A large-scale Technic model of the McLaren P1 hypercar with close to 3,900 pieces. Like other recent Technic supercars it includes a working engine and gearbox, so the build is as much about the mechanics as the looks, and the finished car is an imposing display piece.
The cheapest price is about a third below RRP across eight shops we track, which is solid. We have, however, seen it roughly 13 % cheaper than today, so it is not at its lowest. If you are patient, an alert could pay off; otherwise today's price is still well below launch.
