True in most respects, Johnny. But, his Tahoe estate was worthy of the turn-of-the-century Robber Barons, if not mid-century Mafiosi. That's how he thought of himself: a "Captain of Industry."
Since you mentioned cars (an old favorite subject between you and me): FFC was fanatical about details, and nowhere more than in his selection of cars. Note that, when Kay is stopped from leaving the compound, she'd driving a plain-Jane '57 Buick Special wagon--not the higher-end Century wagon. On the other hand, when Michael returns to Tahoe, he's being driven in a '58 Chrysler Crown Imperial limo--one of only 36 made by Ghia of Turin, and, at ~$13k, the most expensive domestic car of the year.
