A few ideas of mine
Garages/office-Places to work on your car when you start out you could have something like a small house which you can walk around your house could hold a small number of cars in the drive as the game progresses you get better garages like full blown warehouses with testing facilites as with the office at the start it could be just a computer with e-mail etc but as you progress it could become more of a business aspect involed (once this doesn't take up too much of the game)
Business- I think you sould be albe to make money by other means then racing so as a race driver you could sign deals with racing teams aftermarket companys etc these will give so a "Wage" so the better you perform the more money you get they will also give you cars garages and offer discounts on certain goods
