LEGO Technic McLaren P1 42172

The Technic McLaren P1 is a 3,893-piece, 1:8 scale model for adults, over 23 in. (59 cm) long. LEGO lists a 7-speed gearbox with a shifter drum, a V8 piston engine, suspension, an adjustable rear wing and butterfly doors. Each set carries its own serial number, which LEGO says unlocks online content.

Brickset's review, written on a copy from LEGO, ranks it above the earlier cars in the series. It reports a chassis with no flex, bodywork with no stickers because everything is printed, and a build of exactly 1,000 steps across two manuals of about 400 pages each. The reviewer also calls the gearbox largely pointless on display: you can barely notice its effect without attaching a motor, and the rear bodywork does not lift off easily to show it. Brickset has no member written reviews of this set.

It suits an adult who wants a long, mechanical build and has room for a 59 cm car. Skip it if $449.99 is hard to justify for a display model, or if you want to see the mechanisms working once it is finished.
