I disagree with some of the above.
Full time you will do MORE, if you borrow you will do MORE, if you buy higher value stock you will earn from it MORE, you have a chance for finance income AND for much better part exchanges.
DO NOT stay small if you have a chance and desire to grow, you are just wasting time and opportunity. The following 5 years will give a lot of opportunities to clued up dealers that are willing to put in the investment and the work.
