The "Chryslus Corvega" mod for Fallout New Vegas adds up on the Fast Travel mechanism. You can't fast travel out of the blue anymore, you need to find a car to do so. And that car is a Chryslus. Yes, just like the one you used 200 years ago, in Fallout 2. But first, you'll need to complete a brand new quest in new and updated old environments. Only once the car is yours, you can Fast Travel, but only with fuel you'll have to find around ! Among other things, yes you'll be able to stack your stuff in the trunk, and no, you can't actually drive the car.
