About vehicles - I wonder if this will replace fast travel between towns? Probably not, but I really hated how Easy fast travel made the game and used a mod to disable it. The wasteland seemed so much more realistic to me when I had to hoof it everywhere, and couldn't cheat my way home (my personal view only). I think Vehicles will do alot for folks like me in not even needing to fast travel when real vehicles are around

I love the rumor about trading parts, and this brings way back into the 1980's when we used to play Car Wars. In that old board game you outfitted your vehicles with different engines, weapons, tires, etc and that had effects on what the vehicle could do/how powerful it was. It was a great game for its day, and the rumor about vehicles that you can improve is exciting! I hope they go a ways with this, and allow weapons to be purchased/mounted on them.
I also wonder, with vehicles, if there will be any Quests/missions that center on them. I can just imagine an urgent mission given to me in which critical supplies were stolen and are now being raced-out of New Vegas via train - the only hope the player having being to get in a car, chase down the train and stop it (violently or otherwise). Mmmmm.
