Well, except for a couple of things. There is no electricity cost. The resale number is made-up, financing has nothing to do with anything, and the comparison vehicle is arbitrary.
On the other hand, the gas car will probably cost more in maintenance. And he didn't add in all the incentives. Maybe because he pretends to be a capitalist, but only when it suits his greed. Apparently, he has no problem taking money from other tax payers that don't buy electric cars, like any good socialist thief.
It's truly the only way Scotland! America...if you can't beat, don't PAY for them...join em!
Electricity is factored into the Volt annual "fuel" numbers, per the government average. That cost is a blended average. I could do it another way: 40 miles for a charge, a charge costs $.09 * 10 (Kw), or $.90, which is $.02/ mile for fuel. On the analysis above, we're looking at $.07/ mile for fuel/ energy...so if anything, it's an overstatement of energy costs.
Financing has alot to do with things. Money costs, well, money and thus when your capital cost is 0%, it's free money, so long as the deal is a good deal. I did not factor in any Honda incentives, however I could not find any out there when I looked according to google and edmunds. I also took Edmunds true value (what others are paying) for the car, new.
My used values are derived from real world numbers and extrapolated. In fact, many times I'm able to call the used value of vehicles I understand well better than KBB is, because knowing the market and the demand helps a lot. I could be off on the Volt resale in 5 years, however as I anticipate the credits to phase out, that will put a price floor on the car that I didn't anticipate in my numbers. What we've seen in the used car market is that fuel efficient cars are selling at a multiple above the gas users. I had to make some assumptions on the 5 year value of the Volt, however that was based on what's happening in the 2 year numbers. Mind you, when lease cars come back on the market, that will drive values down decently...but not a huge amount as normal cars do (which is really why the Acccord does so poorly on real world numbers) as the Volt's haven't sold particularly well. IOW, there shouldn't be a glut in the market place with the earlier models. The key is to get out before 5 years, IMO.
And for the record, I have no problem clawing back what little tax revenue we can. The government takes enough. It's up to the citizen to figure out how to not get fucked as hard...and having a company certainly helps. That's not even factored into this equation, but take either of those vehicles and 179 deduct them and the case for replacement every 3 years is very strong.
Like I said, I hate to admit it, but there wasn't much of a comparison when I was replacing the CTS-V. I loved that car and I loved the idea of more insane HP, but it just doesn't make sense for how I drive and what I do. We replaced my GF's with a much more performance based convertible, non-hybrid type and while I think that will hold its value well enough against the market, in hindsight, a hybrid would have been a better choice for her as well. We'll probably go that route when we sell this latest car of hers.
