"Right away when opening this set you can tell Bugatti and Lego put their all into it. It is presented with so much more prestige than your typical Lego set. Inside the box is a collection of smaller boxes and the instruction manual that make up a picture of a Bugatti. The reverse of these has another picture as well. So right away you can tell you are getting into a set that Bugatti and Lego put their all into.
There are two instruction books included and the division of bags into different numbered boxes makes it easy to follow along and stay organized. It took me around 12 hours to put it together and it was quite enjoyable. There is a podcast they suggest listening to while building. I did not listen to it, mainly cause there was other content I felt like having on.
One of the more difficult steps was when you need to merge the front of the car with the back. You have to line up the drive shaft and a few other moving parts. The instructions tell you to make sure certain moving parts are placed in a certain direction but there is not much guidance on what to test once these are together to make sure everything is working. I would suggest putting the wheels on at this point for testing on a flat surface. The wheels should rotate the drive shaft and if you move the shift knob towards the engine, then the pistons in the engine should move when the car moves (I believe the shifter is on at this point). After you test take the wheels back off.
It looks amazing when put together. I don't think I will take this set apart or rebuild it like I have with others. The long tube pieces that make up some of the curves of the car seem like they could get really messed up with repeated builds.
Overall, it is a set I would definitely recommend to anyone that enjoys both cars and Lego."
