well, if you would like to go into cutting nasty hair off, you should go with the barber business, good luck makign more than $50 an hour... where as the autmotive business guves you a whole range of things to work with. everyoen has to have a car, and cars break down quite frequently. the car shop would be the way to go, in my opinion. everyone does have hair though... def a car shop. income=HIGH!!!
