It took me a year to get the wholesalers to talk to me, You have to get established, sell your dealer bought parts at a 10 percent markup, then when you start buying wholesale, mark up 35%, this will keep your profits in line, than when you get to dealership status, you can mark them up to over 50% mark up, ( i hope i never become one)I like helping my customers, not taking advantage of them, Like I always tell them, "I am in it for the fun"
