What File Type for Car Mods

Hello all,

I've recently been messing around with CAD and I'm making a model of a Blitzen Benz style thing. Whilst making it I was thinking about how cool it would be to have it in AC so what about if I were to make the model and upload it here in the correct AC model file type could someone take it and try to make a proper mod out of it?


Here is a WIP render, the interior, suspension and rear bodywork isn't done yet.
