This kart was run as a TAG. If your new to karting, you could start with a 4cycle CLONE engine. The local club has a healthy feild to race with. After you get used to things, I'd pickup a Rotax (configured in the photos above is a Rotax engine). Think you can pick up a CLONE package currently for around $199.
The kart will fit in a full size pickup or compact (removing front nose, body work and rear wheels). Some folks run a small flat bed trailer behind cars. Harbor Freight sells small flatbed trailers for around $400. I was looking into that set up when I was driving my Legacy.
Take a look at this link,
