In his twenties, and earning £60k from engineering? - Tell him to stick with his job in F1. Or if he can, take some of his work 'home' with him, and run a separate specialist engineering business from the farm. While he might think "the grass is greener", the rest of us are trying to diversify away from the core business of farming. So yes, rent a farm to use as premises, but as for thinking he'll make a fortune / maintain his lifestyle pulling tits, FFS NO!
