...and hey, i want that little red corvega roadster as shown in the trailer's prewar part (when they flee towards the vault)

aaah, the good old days...

I wonder how long before the "Pretty Piper" mod is made.

way after the "piper pimped" mod, mate... ,-)

As soon as possible, I would imagine. The modding tools won't be out until early next year, but some mods are possible without them.

I'll probably use one myself if the results are interesting (as opposed to the typical fashion model makeover that's popular with companion alterations).
