Take me to the stake, but I'm not a fan of the Bugatti Veyron. I just think the design is a bad pastiche of old and new. But I'm a fan of watching things being carefully made and a fan of strange industrial machinery like the trolley above, used to join the different parts of the car. So satisfying.
If you have the time, watch this How it's made on the Bugatti Veyron. Incredible craftsmanship.
