I'm sure you are probably right, but it wouldn't surprise me at all to hear they changed out power plants and refreshed some systems and serviced brakes, tires, fluids, and any other consumables as well as going over it with a fine tooth comb. When we did annuals or 100 hrs, we would strip out the interior open up all the panels, change fluids and filters, wash it down and in general make sure everything was ship shape, on aircraft equipped with a nitrogen system to blow down the gear, the customer would do that, and we would service that system, any cracks we would drill a hole to stop the propagation of stress. Every flight has a squack sheet, and maintenance and engineering are downloading data making sure that everything is up to snuff. You have to remember this isn't someone else's rehashed warmed over bird, and I wouldn't be suprised to see two and possibly even three make an appearance.
