Oh.... one more little tid bit....at this juncture of your career I would stick with the dealership, and don't (expletive) where you sleep.
Most employers and especially dealerships frown on that. Could be a career ending decision, and that can follow you for a long time.
There will be time enough later to go independent. (that comes with a whole different set of worries)
Good luck, soak up all the training they offer you, and every day on the floor can be a learning experience.
