Get it delivered. There are even services where they'll come to your house and fill up your car - the concept seems popular with the wealthy, especially as it avoids rolling into a gas station in a ride that screams "I Have Money".
Arfcom GD has a thread on this very subject a couple of days ago.
Edit: how I would do it, if money was no object.
Concrete slab wi bollards to protect tanks , tank installed end out to maximize space.
1-2 500 gallon tanks for diesel, because diesel keeps a llloonngg time when treated.
A single 500 gallon tank of 93 octane ethanol free gas.
A single 300 gallon tank of either "Sunoco Blue" or E85.
All tanks will have their own 120v pumps, with fine filters on it, and filling them, funnel type "Carribean" fuel filters will be used. The idea is to keep as much garbage out as possible.
Putting ball valves on the bottom of each tank and letting the tank sit for a week before draining the seperated water out, is a good idea too.
