Build your own McLaren P1 and pretend you're a billionaire for 20+ hours. This 3,893-piece LEGO Technic set delivers the real deal: working 7-speed gearbox, V8 piston engine, adjustable rear wing, and butterfly doors that actually open. At 1:8 scale, your finished model will dominate any shelf (59 cm long, so clear some space). Every brick counts toward authentic engineering details that'll make you feel like a proper mechanic. Includes a unique serial number for exclusive online content. Perfect for adults who love supercars, precision building, and having something cooler than their actual car to display.
