This is the plane that I flew many times over New England.
I flew others as well and never owned one of them. They are rentals, and most medium sized airports that aren't major transport hubs have a rental place.
To take a plane out on your own they need to see your pilot's license, and they'll rent a plane to you often without a referral.
The rates are usually by the hours of flight time, not for the amount of time that you have the plane, so that is a consideration.
The Cessna 172 below is a 4 seater and can carry luggage behind the last row of seats. It has a 150 HP engine.
