One of my clients uses his airplane for business travel. He earned his private pilot certificate a few years ago in a Cessna 172 then bought a single-engine Piper piston.
When he lands at an airport with a flight school, he seeks out the chance to fly a new-to-him model of aircraft for the experience. It’s his way of keeping his learning skills sharp. This activity has put him in a variety of Cessna singles such as the Skycatcher and a C-152, along with Cirruses, Diamonds, and a smattering of light sport designs.
