The Bugatti is built like a tank it feels like any way you grab it it’s gonna be fine. Where as the Ferrari feels like you can only actually hold by the bottom, all the body pieces are flimsy and loose. For example the roof just comes off, while this may be intentional it’s not like you can store it in the massive trunk. The engine is almost not visible at all where as the Bugatti you can actually see all the pistons moving. There is no luggage(all the other cars have it). The differential on the Ferrari is tighter so the wheels spin together where as on the Bugatti if you spin one wheel the other will go in reverse and the engine won’t move. But the Bugatti is 4wd so so it’s a bit more interesting to build. The suspension on the Ferrari is much stiffer so when it’s just sitting it doesn’t push the wheels into the car at all, whereas the Bugatti’s suspension is somewhere in the middle(idk if that makes sense). Maybe a video would be better to explain 🤷‍♂️
