700 is only the cost of the charger. How much will that increase your electric bill every month? And when you take those trips and charge in new places, how long will he have to wait at each stop to charge?
ETA: So I'm doing the math - I spend about $140 on gas per month in my gas guzzling Odyssey, or $1680 per year. So in a Tesla, I'd spend approximately $400 per year, saving me about $1200 per year (about three of my current car payments). Over ten years, I'd save approximately $12,000. But Teslas are about $100,000 to purchase, and given their performance status and desirability for theft, I'm sure the insurance will cost more. So if I were to give up my $35,000 honda to purchase a $100,000 car that saves me only $1,200, it would take me about, I'm estimating, at least 30 years to see a return on that investment. What you save in gas can't possibly be worth what you would spend in car payments and insurance, not to mention that you'd be trading in a 5 minute pit stop at the gas station for an hour and 12 minute recharging time. I can't for the life of me see the economic sense of that at this stage of the game. I'm all for going green, but this is illogical, and unless you're willing to also insist on solar panels, rain barrels, composting, front yard gardening, and all the other green things, I can't see why this one. I appreciate that he admires the founder. A lot of men admire Hugh Heffner for the empire he created. Wouldn't really want my husband emulating him, though...
