I went to visit the D.C. store a few weeks back to meet Shaun Phillips and check out the Model S on display. An hour later, I found myself talking to customers about Tesla and my experience with the Roadster, had a girlfriend picking out Model S paint colors while holding a bag full of Tesla clothing and was sold on the Xenon headlamps. I thought Apple had sucked me in. Xenon's arrived today. Is there a market for the old headlamps?
