So you'll pretty much be applying as Internet sales for a dealership? If it is Good Luck to you. The Car Sales Biz can either make you or break you. Best of Luck.

Oh plus don't feel to bad that you work for your dad. I myself work for my uncle and in the process of finding a better paying job. My uncle understands that if i leave its for my best and that i can acheive higher if i do leave. As long as you and your father have an understanding that you want a brighter career and to further educate yourself in the workforce then im sure he won't mind you leaving, just let him know in advance so he can atleast find someone to replace you.
