BTW, the S Model starts at around 50k. There are choices of models and prices, like most all other vehicles.
The range goes down in cold weather, both because batteries deliver less power when cold, and because energy for heating the interior comes from the batteries rather than being a free byproduct of engine operation.
The batteries are a large percentage of the total cost. Tesla is evasive about the cost of replacement batteries. You WILL need replacement batteries eventually.
Bottom line: The Tesla S is a very expensive toy right now.
I would also add that, with the battery packs being much of the cost of the car, as Tesla cars get older and start needing expensive replacement packs, Tesla cars will be a prime target of car thieves, who will deliver them to chop-shops.
