Not that I'm considering doing this, but if one were to consider it from a pure capitalist mindset, doesn't it make sense to buy a Honda Clarity PHEV (lets say base model for now), and drive it for a year and treat it gingerly, while collecting the tax credits and rebates, and trade it in the following year and buy a new (same) model one year newer than the previous and collect the tax credits and rebates and do the same thing year after year? Key Assumptions: 1) you are in a tax situation which will allow for the full $7500 federal tax credit year after year; 2) you don't care about conspicuous consumption and the effect on the environment; 3) the Clarity PHEV will continue to be available as new models at roughly the same MSRP and sales price year after year; 4) trading in rather than selling to a third party, although the 3rd party would likely be more profitable. I saw a paper today (https://www.sciencedirect.com/science/article/pii/S0301421518306669) that described depreciation of BEVs, PHEVs, HEVs, ICEs relative to each other and then looking a the kbb estimate of my 1 year old Clarity, there was good agreement (current trade in value averaging ~$20.6K). If I can get a new model at around say $29-30K (USD) every year, and then recover the tax incentives (minimum $7500 USD). After say 4 years of doing this you'd have absorbed $30K of tax incentives, plus you'd have a new car all the time (no battery life worries to start with), and after four years you'd be sitting in a car that is worth say ten thousand $ more than a four year old version of the same car. The positive trend would probably get better the longer you could keep it up. Again, I'm not considering it, but in a way the numbers seem to absurdly favor trading in every year, do they not? Yes you take the depreciation hit every year which is really steep, but the tax incentive and the discounts that seem to be offered appear to offset most or even all of it. In fact I looked at the current dealer discounts in MA where I live, and it is actually MUCH cheaper to buy a new Touring model rather than a base model thanks to an $8500 (!!) discount at Hyannis Honda. Bizarro world. I am a believer that collectively we use way too much resources, so while these incentives are great to allow BEVs and PHEVs to make progress in sales, I think the tax credits and rebates should be limited so that people don't have incentive to game the system (please refrain from political commentary). I think it is a moot point since the Clarity PHEV probably has a very limited future, but if it is supplanted by a model that gets the same tax incentives (or better) the logic may still hold. Anyway, just thought I'd share... (I know I am leaving out sales tax, TTL, doc fees, extra insurance, etc. so at best it may be a wash from a money standpoint but still you'd have a new vehicle perpetually and no need for an extended warranty, nor yearly maintenance costs). I can do some more thorough cost analysis if anyone is interested. The numbers will probably vary quite a bit from state to state depending on rebates, discounts, availability, etc.
