On a 2005 car with 2000 miles, I would also recommend that you do a transaxle fluid change at the same time (pans off). The first transaxle fluid change (recommended at 1 year, regardless of miles) will yield some pretty nasty looking oil. Subsequent changes will likely show cleaner "old" oil. The transaxle fluid change is straightforward but make sure they pull the plug with the screen (driver's side) as well as the plug with the magnet (passenger's side). Both screen and magnet should be thoroughly cleaned before re-installing. The transaxle will take just under 4 quarts of oil - fill-plug on Driver's side of transaxle. Expect the transaxle fluid to cost ~$38-$40 per quart and make sure it is Part number: XT-75W90-QGT. Don't use anything else in the transaxle.
For the engine oil, make sure they use XO-5W50-QGT. Some dealerships may advise that Mobil 1 is OK. It is not. Mobil 1 does not offer the proper 5w50 viscosity as required for the GT motor. They should remove all three drain plugs, and they should use a torque wrench for re-installation. As both bottom pans will be off, I always take the opportunity for a quick visual inspection. Look for any oil leaking from the plastic oil pump belt cover. Inspect the power steering pump for leaking (a residual 1-2 drops of red fluid on the pump with no large spot on the pan is normal, in my opinion.) Finally, inspect the OEM engine oil cooler for any signs of leaks - some have had manufacturing defects.
The Ford tech should follow GT-specific priming procedure to prime the dry-sump components prior to re-start.
