LEGOTechnic Bugatti Chiron 42083 Race Car Building Kit and Engineering Toy, Adult Collectible Sports Car with Scale Model Engine (3599 Pieces)

This was my first Technic build, and as an adult let me tell you this kit was REALLY fun to put together. It took me 8 days of building multiple hours per day to complete, and I enjoyed every minute of it (well, except for the minute I realized I had built the spoiler assembly incorrectly about 30 pages after the fact and had to dismantle the rear of the car to fix it, LOL!). It's definitely addicting and satisfying! And even though I had seen many pictures and videos of it before purchasing, it didn't strike me how LARGE this model is until I had it in front of me. That's a good thing!As for reviewers claiming they had pieces missing, let me just say that not a single piece was missing from mine and I had a good number of extra pieces (mainly small connectors and such) at the end. There were a few times where I started to panic thinking a piece was missing, but then realized that I had just overlooked it in the sea of small pieces (often because the piece was standing on its side or hidden under another piece). Once I literally stared at my trays of pieces for 2-3 minutes before spotting the "missing" piece.I do agree with the reviewers that say the doors are a bit cheap feeling in light of the quality of the rest of the build. I'm not sure why they couldn't have stabilized the hinge area further and also made it so the door stops flush instead of being able to push it too far in. I'm sure if you have a store of Technic pieces, though, you could come up with something on your own to do this. I also agree with those that say the front end could do with fewer "gaps," but it's honestly not that bad. One thing I haven't seen mentioned that I thought was peculiar is why the steering wheel wasn't flat-bottomed like in the actual Chiron.But none of these minor complaints warrant taking away a star. This was definitely worth the money, and I couldn't help but also buy the Porsche 911 GT3 RS. My suggestion is to take your time while building this and frequently closely compare what you have in your hand to the illustrations to be sure every piece is oriented correctly and every connection is in place before you get too far ahead.

Good product. Exactly as expected. My wife had a blast assembling this.

Words of my husband:Though expensive, the Lego Bugatti is a joy and experience to craft and build; if this duplicates automotive engineering than both the car and Lego designers are pure geniuses, and you learn to respect the design as you build. This is a fun project to zone out on and do a couple hours at a time here and there. The packaging itself is pristine and professional, everything is arranged and categorized beautifully to where you can plan it out. Without spoiling too much, there are two(!) manuals to building this beast! And the manuals themselves are full of photos and art and footnotes from the designers. Though the exterior is very flashy, my favorite parts to build were the engine, vastly complex transmission, and gearbox; and the way these all fit together seamlessly will blow your mind if you're into design and engineering at all. I rarely had trouble or difficulty, but definitely check twice before connected (measure twice, cut once, as a previous reviewer said) as there were a couple times I had to retrace my steps; the car is designed as some parts you make at the beginning will have no purpose until later, and it is just MAGNIFICENT how they all fit together purposely. I also had no missing or flawed pieces, my kit came with about 20 extra pieces actually! (Probably a later print). I really enjoyed my time with this, something best done late at night with some vibey music in the background, unwinding from work. 10/10 recommend, would buy again! I intend on checking out the other kits such as the newer Lamborghini, the Porsche, or the Land Rover.

What a job to put together and lots of fun. Advanced builders onlyLego does a great job on customer support

I loved building this, it's super in depth but really easy to build, just takes time and patience.Really nice weight and the build is sturdy.

I just can't say enough about this Lego Technic kit. What a wonderful experience. I'm 65 and retired. I spent most of my career servicing large, expensive, complex equipment. At the start of the pandemic, I purchased the Saturn V kit (1969 pieces) to kill some time. I built it and disassembled it twice. Now I have the Lego bug.So......I ordered the Lego Technic Bugatti Chiron.Building the Chiron was a challenge , but not difficult. Keep in mind, this is not the traditional block design Legos. The Technic sets are mostly beams and pins, with some traditional Lego elements. This makes for a much stronger build and opens up new design options for the engineers. I actually enjoyed it more than the Saturn V build (and I'm a huge NASA nerd!).If you take your time, triple check everything, you'll do fine. I took my time and finished on the 6th day, working on it a few hours a day). When I finished, I was thrilled to see that everything worked. The speed key, the 8 speed sequential transmission, the 16 pistons moving correctly driven by three camshafts, the rear wing, and the steering, I wholeheartedly recommend this to any car fan, Lego fan, or anyone that enjoys a good challenge.It should be noted; I think a 16 year old would have to be exceptional to build this kit alone.Kudos to Lego, you have a new fan!

This was very challeging and a great build. The finished product is show quality and ready to be displayed.
