That's kind of impressive. If they noticed it without you clicking "BUY", it would be a little scary. Like the salesman who ambles up behind you while you're browsing and just happens to know your favorite interior color from when you browsed a year before.I was poking around the design studio the other day and even pushed the "BUY" button for a nicely optioned roadster. Just to get some Euro prices and doing an estimate of current USD to Euro price relations. Tesla contacted me via email, they noticed the activity and asked how they could help. Wow!
