I think people overestimate how much the car has been improved. Every single annoyance I have with my 2015 70D still exists with the 2017 100D, and likely won't be addressed until well after the tax rebate runs out. It's going to take the new guy from Volvo a lot time to fix what I want fixed. There have been improvements, but the focus has been elsewhere. Where it's focused on performance in a straight line, improved battery technology (100KW battery), or the hardware for autonomous driving. Those are the main bullet items people see, and don't count the numerous enhancements/fixes people don't see (that are to reduce problems and to speed production). There will be, but those enhancements (to the body shape, and interior) are on a much slower upgrade track. Until the Model 3 comes out it's really about how much value someone puts on AP2 versus AP1. Much of that value right now is future predicting. As to leasing versus buying it really comes down to miles. This car is tremendously easy to put miles onto, and it would be really tough for me to keep within the limits of a normal lease. Plus if I finance then I get the $7500 rebate versus it being built into the lease. I also haven't seen really good lease deals for it anyways. When I financed my 70D things were a lot different. Washington State had a sales tax exemption that was about to expire Tesla had a resale guarantee that guaranteed the price of the car, and this was only applicable to ones financed through Tesla (or through the approved vendor). So I got those things and free supercharging for life. I'm not exactly keen on upgrading for promises on AP2. I'm more likely to do the smart thing, and ALWAYS the smart thing of keeping it till the wheels fall off. Where you don't get suckered by the new.
