I think it would be really, really awesome if there was like an old lamborghini or an old ferrari. For transport and so you are able to cruise around. They did say that Vegas was not so damaged, by the bombs and by the looks of it, it seems that they have rebuild themselves, perhaps to their former glory. So what do you guys think? Would it not be awesome if we could drive around like mob bosses?

They wouldn't have sports cars like the ones we have today. The closest thing to sports cars at that time were Racing cars and convertibles, and even they look really retro.

Yeah a ferrari wouldn't really be able to drive around in the wasteland.
I want to see a dune buggy.
Also we've already got a few active threads on vehicles though.

Still the cars could be really injured and old, and perhaps you can do a quest to make them better. You know getting better parts, paint, etc, etc.

Use one of the existing topics like the one Suffca linked please.
