Car Designer: bodies organization

I've seen that there's a thread about this question without a clear 'solution'... or answer.
After the update (more bodies), and having read that you are planning a bunch of them, I think that would be good to give any idea about that matter.
I also have seen that in Automation's cars directory you have the cars organized by size and decades so from something like that it could be like the pic below.
The bodies would be sorted by decades and types.

ED: Btw, just thinking about decades..., there would be any kind of penalization for creating a XXI century car with a body from XX century? (or an older decade than the current - in-game - decade).
