One of our members recently built the Ferrari Daytona SP3 (42143) and was kind enough to send in photos of the finished model. At 3,778 pieces it sits near the top of what LEGO Technic has produced in terms of complexity, and it shows in the result. If you have been considering this one, seeing it through a builder’s eyes is the best way to decide.
LEGO Technic Ferrari Daytona SP3 (42143)
The Daytona SP3 is one of Ferrari’s Icona series cars, inspired by the 1967 Le Mans racers and limited to 599 examples in real life. LEGO’s version captures the low, wide stance and the curved red body panels surprisingly well for a Technic model. The V12 engine with working pistons and the butterfly doors are the two features members mention most, and rightly so.
Good to know: this kit is retiring from the library in July 2026. If you want to build it, now is the time to get it booked.
The build sequence is part of what makes this kit satisfying. You start with the V12 engine, which forms the spine of the chassis, and build outwards from there. It means you are never just clipping panels onto a finished structure: you understand what is inside the car because you built it first. The engine block itself takes a while and every piston is individually connected, so by the time you have it done you are genuinely invested in the rest of the build.
The one section that will slow most builders down is the front end panel clips. The curved red panels that define the Daytona SP3’s nose need to lock in at precise angles, and getting all of them to sit flush without any gaps takes patience. It is not difficult, just fiddly. Once the front end is set, the rest of the body comes together well and the finished model holds its shape solidly. For a Technic set, the body proportions are as close to the real car as you are going to get at this scale.
The V12 engine section is worth taking your time over. All twelve pistons move as the crankshaft turns, and it is one of those moments in Technic where the mechanism does exactly what it should. It sets the tone for the rest of the build.
A big thank you to the member who sent these in. If you have built a kit from the library and want to share photos, get in touch at [email protected]. It is always good to see what members make of these sets.
This is exactly why I like putting member builds on the blog. The official images tell you what a kit is supposed to look like. Member photos show what it feels like once someone has actually sat down, opened the bags, and worked through it.
If you have just finished Ferrari Daytona SP3, send over a few photos. It does not need to be a full studio setup. A clean table, a finished build, and a few notes on what stood out are enough.
