While I wish you much luck, electriclove, your characterization of Roadster owners as forgotten and overcharged immediately turned me off.
One thing I really insisted on in business was that we not use the competition as a reason to buy our product - our product should be good enough to stand alone. If your service is better than Tesla's service, then that's the best advertisement of all. But when you have owners here responding and saying we're not unhappy, that's a good data point that should be considered. And when you talk about $10k PEM repairs, but an owner tells you his was replaced for minimal cost (2nd owner, definitely not under warranty), that should be applauded.
Could things change? Sure. But Tesla has not forgotten their flagship product in my experience (and the experience of some others who have posted here). There are definitely some customers that have gotten under their skin and perhaps haven't had as positive an experience.
Bottom line for me? If your service is better, you'd get my business. But talking down Tesla is a small red flag for me. You shouldn't need to do that to get business.
