Thanks Tom - very good input. You are right, I am somewhat new to Bimmerfest. While I had used it some as a resource before buying our car this past summer, I had never actually signed up and posted anything until now.
Yes, I do need to do a lot more research and detailed business analysis. That was sort of my point in actually making a post on here - just to hopefully hear a few thoughts and perspectives from folks like you. Then take some of that information, ideas, and concerns to help me with the analysis and/or business plan. This is not something we're going to do real soon. Most likely would be 2 years from now or so.
I probably didn't articulate my "plan" very well, but I wasn't thinking of marketing exclusively to ED customers -- just thought that might be a nice niche market I could attempt to tap into to some degree or another.
Right now, it's mostly a vague but intriguing concept rolling around in my head.
Thanks again for the reply and feedback.
