Agree, all relatively modest dwellings and possessions.
To put it in perspective Manchester United have just agreed to pay the wages of Nani (a player they no longer want and have loaned out to FC Porto for a year) of £4,800,000. Yes, almost 5 million pounds for the year. That implies he's been paid around £30 million since he joined United.
I doubt whether a Sprite Caravan is top of his shopping list.
Cristiano Ronaldo, when you take his sponsorship deals into account earns over £50 million a year. He could afford the top-of-the-range Sprite, with all the extras (blown heating, electric flush WC, LED lighting, possibly some electric "movers" to help him manoeuvre the caravan into his driveway ).
Also, i think you'll find that the correct 1970's term for Wives and Girlfriends was, in fact, "Birds".
