Boats do count. Any vehicle.
I did consider the millenium falcon…but all the repair work they had to do in the empire strikes back made me reconsider.
Kitt is a great suggestion and it made me mad that I didn’t think of that or of the bat mobile
Enterprise E with a full crew compliment of hot alien space babes.
From “The Great Race”. Professor Fate’s Hannibal Twin-8 
This was going to be my second choice (TARDIS being first). Guess I’ll go with the Mach 5.
3rd-ing the Delorean from BTTF! So I can go back and tell my Dad, “F-u, I’m moving to Walpole.”
Is this limited to movies? I want George Jetson’s car! It flies, it floats, it hovers, and it folds up into a two-pound briefcase!
Toss up between the Tardis (time, space and elbow room) and a White Star from the Babylon 5 universe - it’s pretty. 
The Tardis, of course. I hope she would like me … The Doctor’s Wife is one of my favorite episodes. The ending is a real tear jerker. He looks and sounds so lonely.
I want a fully equipped Nimitz class nuclear carrier. Then I’l have it entirely automated so it can get along with a helmsman and an engineer, and of course several excellent chefs. It comes with an entire air wing, but I’ll get rid of most of the planes to make room for the world’s largest mobile dance floor and the only nuclear-powered sound system on the planet. I keep a couple of helicopters to shuttle people to and from the ship, and a dozen F-18s. One in case I have to get somewhere really fast, and the rest if I have to kick some pirate ass.
It’ll be a babe magnet and I’ll have a guest bedroom for every babe. Because it’s nuclear powered the only times I’ll have to dock is … um, not in my lifetime.
An AT-AT.
I’ll just park over the building.
Slave-1
Call my needs modest, but I always though that The Cyclops from the hugely underrated comedy film The Big Bus* would make an awesome RV! (minus the nuclear reactor…) 
*If you ever get a chance, watch this film. It’s the Zucker Bros Airplace! nearly five years earlier!
I’ll take the African Queen, and then I’ll be the only one here who has something that anyone can fix when it breaks down
I will still take the last of the V8 Interceptors fromm Mad Max.
The Trans Am from Thunderbolt and Lightfoot. I already owned the '73 455 Riviera.
I don’t drive, but KITT is too sporty for me. I’ll take Herby, the Love Bug.
Stephen Hawking’s wheelchair (it was in a ST:TNG ep)
But then I guess I’d have to drag him around behind me…
TARDIS, for sure. Best camper ever!
Failing that, does a Star Trek transporter count? Or how about any ship with a transporter on it. That’d work; I’d just need to find someone to stay on board and activate it for me on demand. Shouldn’t be too hard. If I can get my hands on a stash of Magic cards and an unlimited supply of replicated Doritos on board, I’ll have all the geek boys I need at my command…
James Bond’s Aston Martin DB5.
