Stads,
In answer to your question, yes on the tax breaks. There a couple different rebates (in the thousands) for buying new, in addition to the federal tax rebate (which was quite nice).
In reply to your post, the one thing I'd counter with is that my wife's car (which is a plug-in hybrid, so not entirely electric) is 100 percent covered. All the electric motor systems and components are completely covered for the life of the vehicle, and we have an expanded warranty on everything else. So the car is taken care of. It may be a pain in the ass for the mechanics, but for us at least, we're not out-of-pocket for anything on the car except basic maintenance and stuff like brakes and tires.
In addition, because of the gas savings (my wife needs gas once every seven weeks, as opposed to once a week), what we pay for the car (we are buying, not leasing the 2017 plug-in hybrid), factoring in those gas savings, is cheaper per month, payment-wise, than my 2016 plain hybrid. Add in all those tax breaks, and it made total sense for us, as consumers, to get it.
I'm interested to see in a few years what our options are. The goal is for both of us to be on full electric by 2025 if it is feasible in regard to battery life and where the technology is. The thing about the plug in hybrid that I love is that you just plug into a regular outlet at home. No 220 or special line needed. That kind of convenience is a must for us. So if that is available on full electric models in seven years, that's where we're going. If it isn't, I won't mind going to two plug-in hybrid models, depending on what incentives are in play at that time.
Going Tesla could be an option, but we couldn't afford two of them, unless they are in the price range of a Model 3 (and even then, that's a bit more than what we want to do). But again, bringing it to Tesla to charge, or getting something installed in the garage to charge them, just is NOT appealing.
So here's hoping, come 2025, most of these electric or plug-in hybrid models are all of the "plug into a 110 outlet in the garage, be on your way," variety, and are cost effective. Because we are solidly in love with our 2017 plug-in hybrid (again, thanks Nick, as your commentary helped spur our research last year).
