Well , just to respond to some of your points (and why, for me at least, they aren't unreasonable, but I can understand why for the majority use case, some of your points are):
The price of a model S is not what you quoted. I was surprised and went to look, the base model, after California rebate and Federal tax benefit is 59k (so you were right, just I guess you figured another 10k off that price). Unfortunately, the federal tax credit is not a refundable credit, so for me in my current lifestyle, it isn't very useful. Of course, this is me, not 99% of the target audience. The prices, MSRP btw, are 70k, 80k, and 94k (and that top end performance one looks quite awesome).
I chose the audi A6 because in my opinion, it is similar, with certain benefits beyond the Tesla and certain drawbacks, and it depends on your preference. I love going off driving in the mountains, and so the AWD makes the Audi massively higher performance for me relative to a Tesla. I understand if for you, the Tesla is your car. It has a damn cool interior and console, and I have to say it turns me on a bit. But then again, it's also why I can't (yet) get an EV. I commute on my feet or on a bicycle or at worst, public transport. My car is for longer trips, which I take a lot of. I'm looking forward to the IBM battery tech that gave massive power density increases so I can take these long trips and leave my car charging all week while working. I'd be in heaven when they get this up to 1000 miles so long distance trips are manageable.
YMMV, but I've never had a car that is still in a condition I would prefer to use go north of 250k miles. Financially it made more sense to buy a new one around 200k. But then, we are talking about nicer cars, not beaters.
As to electricity, last time I paid it in the US was in NY, and I ran an estimated ConEd bill. The marginal cost in NY is around 20 cents KWh but your average is much higher because of set fees that are added in. Namely, ConEd tells you to expect to pay 66 USD for 255 kWh in 2010 (I'm sure that has gone up, but not so much to matter). Why does this matter to me? My family and I live a lifestyle that makes being off the grid completely feasible once battery storage (or one of a number of other storage methods) becomes slightly cheaper. Solar panels are already more than efficient enough on my target home to provide the power, but I need storage to shift it around. This means my target case (hopefully in the next couple of years) is I care about the average cost of getting power, not the marginal cost. Here is an example coned bill (http://www.coned.com/customercentral/threebill_D19_ResDual.asp)
The last time I did timing belt maintenance (wasn't on an Audi) ran me 500 bucks. Not cheap, but not the end of the world for something I may replace every 100,000 miles if I'm unlucky. I'd be more worried about needing a new transmission or even just a clutch, as those can be nasty depending on the layout and labor involved. But again, my point was merely every time I see someone comparing costs, it's idiotic. They act like electricity is free, like maintenance doesn't exist, etc, etc. All of it matters and my big point is gas vs electricity is not even that relevant of a switch depending on the car and your driving style.
