This isn't even my own complaint. 2016 Tesla Model S 4-Door | eBay 2016 P90D fully loaded on e-bay (not my car) just had to lower his price to $98,500 due to lack of response for what was a $138,000 just 6 months ago. Only has 6,000 miles on it. Pretty sad. I know, cars are not investments, but to lose 40% that quickly is pretty sad and the downside to being part of Tesla's past, not its future. Clear evidence that each release of new features adversely affects the value of existing cars out there. Great for new buyers, bad for existing owners. But as I said, with the latest changes, I can't see any additional "gotta have it" features coming in the near future, so NOW is probably the right time to buy a Model S and feel good that a MAJOR update won't out date your car in the next couple of months. Like the 2012 Model S, 10/2016 Model S is probably good to go for a couple of years before another gotta have it update.
