There's more. Nappa leather is $1,500, a Tech Package (navigation, backup camera, power liftgate and keyless entry) is $3,750, air suspension is $1,500 and so are the pair of child-size rear-facing jump seats.

Another $1,500 will buy you an upgraded onboard charger of 20 kilowatts, which can add up to 62 miles of range per hour.

The high-power wall connector to feed the car's custom charging system – no, it doesn't use the standard J-1772 plug and socket as does every other plug-in car sold in the States – is $1,200 for all models. No word yet on the price of the inevitable J-1772 adaptor cable for use anywhere outside the Tesla driver's garage.

All in all, a lavishly-equipped 2012 Tesla Model S will run you just about $100,000.

Given that the 2012 Fisker Karma extended-range electric car, now finally arriving at dealerships, is newly base-priced at $106,000, the all-electric Model S may seem to buyers like a comparative bargain.
