John Frank, executive director of the Cessna Pilots Association, says he basically agrees with Thomas' assessment of both the different types of piston aircraft buyers, and the fact that there isn't much crossover among them. However, Frank says he'd add a fourth group to the list. "I have a Cessna turbo 210, because there's nothing being built new, powered by a piston engine, that will perform as well as a 210," he explains. "Some are as fast, but they won't carry the same load. But there are other people, like me, who've held on to planes like the 210 for that reason, who might be motivated to buy a new aircraft, or a newer glass aircraft, because of the other capabilities they offer."
