It would be amazing if somebody did what a lot of people are doing and taking the front subframe, suspension, and motor of an FWD vehicle and dumping it in the back of a VW Beetle or, in this case, a Piccolina. In-game, it would likely be the Wendover/Legran drivetrain. Would make for a monster of a Piccolina, with great weight distribution. Just a fun idea, not pushing anybody to make this, as I know how well that can go over.
that actually seems like a pretty good mod to start off with. I suggest you download blender and notepad++, and have a fiddle around with some Jbeam and mesh files!
Also, I was thinking about trying out the Beam Node Editor thing, got any experience with that? If so do you know about any decent tutorials for the node editor and basic jbeaming+modeling?
