I remember last year I bought a chest freezer. The salesman ask if I wanted it delivered or I wanted to take it cash and carry. I said I would take it home myself. He said "You don't have a Honda Civic do you?" I looked puzzled and said that I had a van with me. He said "Good. You don't know how many people buy large items from here, then they drive around to the loading dock with a Honda Civic and expect it to fit."
Anyway, you are also going to need a second person to help move, unbox, and mount the TV once you get it home. So you might as well find the second person that has either a mini-van, SUV, or pickup truck.
The last 52" LCD I bought I asked a friend to help a few hours before the Florida-Miami football game. I said that once we get it hooked up I'd buy pizza, chicken wings, and beer and we would watch the game in hi-def. He was over at my house in about 10 minutes ready to move the TV. He also showed up with his Playstation 3, a couple of games, and a couple of blu-ray movies.
You can also rent a pickup truck from most Home Depot locations for $19.99 for 45 minutes.
