Placed an order for a new S60 and just saw a late 2014 S85 with Autopilot going for $60,000 on Tesla's CPO site. Couple of questions: 1. Have there been any significant improvements in the last 1.5 years that would be worth more than the larger battery? 2. Which car would you expect to have higher depreciation over the next 4-5 years? Thanks!
