This is the evolution of my Bugatti Veyron. Here you can see what I love most about LEGO CAD, in this case the LDD: Once you finish a version, you copy it and work on the next version. So you can always come back to an idea later.
About this creation
As you see here, I made 20 versions of the Bugatti Veyron until I got to the final version.
There where much more changes on the back than on the front. I only changed the design of the headlights and almost at the end of the design I got the idea for the "horseshoe" grill (I had seen it on another MOC, but I don't remember, where).
