I definitely think it would be cheaper to fly me over to SC and I will take it out for you every 6 months and check its full condition. Definitely cheaper yes.
I do not have experience on this as such, but feel I will be in a very similar position by the end of the year. Parking brake off is a must. In addition to this, I would actually take the brake pads out to put some copper grease (anti-seize paste) on the back of them and generally clean the calipers up in the process. The last thing you want is to get in to drive it again and the brakes seize up and overheat.
If your tyres are old, then I would be hesitant to store them for that long. I don't understand the need to remove the wheels from the car, you can put copper grease on the hubs and leave them on. They will be fine.
You can drain the fluids out except the brake fluid (just change that before its driven again properly in 4 years time). With it being sat for so long, the oil will entirely drain to the bottom of the engine and will sit against various seals that will eventually perish.
Conditioning the leather is a great idea as it will dry and crack over time. Have the car fully polished and waxed before storage too just to give the paint the best protection you can, before you cover it etc. This will also make it far easier to clean off when its taken back out of storage.
One final thing to think about is your rubber seals around the doors, boot (Trunk) and bonnet (hood). Put a slight covering of vaseline on them to stop them from drying out or sticking together over time.
Enjoy your 4 year vacation and your immaculate care on your return.

£1000 a month service costs, before you factor in the 9 mpg average. Then it's just the joyful enthusiasm it has for trying to kill you in any situation, or itself every other day.
