I think the reason Aurthur Weasley could expand the Ford Anglia was 
because he secretly had spent many months working on it in the 
garage... 
I imagine it probably took some time for Arthur to cast spells 
enabling the Ford to have its magical properties, and to expand a 
whole house or even just the kitchen would probably be quite 
difficult.
