I'm ok buying a Tesla on as long a note as I can get; I expect to keep it in-service for 10 years, and operating cost savings (and tax credits, etc.) will make it worth it ($100k for a car is a stretch for me right now, so 6y vs. 4y would be a win). Depreciation still makes my current car a better deal, but if my car suddenly died, I'd probably replace with a Model S (maybe after a period of time on zipcar/drivenow). Otherwise waiting on the rumored S AWD in 2015.
