1/72 is much too small for 28mm, and quite frankly 1/56 models are too small as well. The idea sized vehicles for 28mm is 1/48-1/50.
Ultra modern wargamers are very obsessive over this because they need their vehicles to be as "realistic" scaled as possible. They usually use 1/48 or 1/50 for big vehicles like cargo trucks, tanks etc., the ideal size for civilian cars is 1/43
