I took delivery of an S90D in April 2016 so I'm almost half way through my 3yr lease and have driven it 17K miles, including two road trips of about 2,500mi each. That prompted me to take a peek at what I would get if I was to lease a new Tesla today. I configured a new Model S as close to mine as could be done and the result was a car that would cost $7,000 more than I paid 18 months ago, with these differences: 41mi more rated range A cosmetically different nose cone Better headlights A 400kWh SC allowance rather than my current unlimited SC usage The phone dock that came with my car is now an optional extra AP 2.0 which as far as I can tell just received an update to pretty much bring it to parity with my AP 1.0 car but is promised to become substantially better than AP 1.0 at some indeterminate time in the future. In the last 17 months I've seen these "continual improvements" from OTA updates: Media player functionality and usability declined Ease of use of the all CID apps declined in order to get another 3/8" of map area in the car's direction of travel. Driver profiles linked to key fob (something I had in a 2012 Lexus) And I got a recall notice for a potential defect in the parking brake which has not been resolved after five months because the SvC does not have parts. In all fairness, the difference between model years in a Mercedes/BMW/Audi/Lexus is not always compelling either, but they definitely always do something that enhances the ownership experience. Maybe I'm seeing the glass half empty here, but it seems to me that all that happened is I would pay more to get a bigger battery, something I would not otherwise choose to do, but would now have no choice. Tesla has clearly struggled to bring the AP technology in-house since switching from Mobileye and thus far I see no reason to think they are likely to surge forward any time soon. I have to say I have very mixed emotions that Tesla has done nothing to make a new Tesla more compelling than my current car. Disappointed on one hand that Tesla has done so little with the Model S in the last 18 months, relieved on the other hand that I can look elsewhere to help stimulate the economy!
