As a yardstick I use the car rental biz. You go to Hertz, Sixt, Europcar etc to rent a motor for the weekend. You go to Waltham, Denham, Elstree, Goodwood etc to rent a motor with wings for a few hours.
The requirement is nearly the same. Good price, good car (plane) good service.
Already, differences are coming to mind. Even the worst airport car rental office is better than many aero club ops rooms. Prices? Cost plus or what the market will stand?
Good service? Hhmmm. I'll leave that for you, dear reader, to reflect on.
I'm not even going to duck!
