Let's assume that it's a high-end luxury sedan, not a low-end family sedan. Unless gas goes up to $100/gallon, there's no way you'll save money by buying the Tesla over a affordable mid-size like a Honda Accord or Ford Fusion. So let's compare that to a Mercedes E-class. According to US News(http://usnews.rankingsandreviews.com/cars-trucks/Mercedes-Benz_E-Class/ http://usnews.rankingsandreviews.com/cars-trucks/Mercedes-Be...), the average price out the door is about $48,000 for the model with the fewest options. Let's round that up to $50,000, because we want alloy wheels or some other additional feature. The mileage of the car is 24 highway, 17 city, so let's average that to about 20(a bit more city driving than highway). So that's $15,000 in gas over the 5 years(30/20=1.5). So the total cost of the car, not counting other replacements, is around $65,000. That's still $15,000 less than the $80,000 on the Tesla, and you're not going to spend $15,000 on car washes and other parts(brakes, oil, etc.) in that time. It should also be noted that if you need to buy replacement batteries in that 5 year period, the cost increases to $100,000. EDIT: I didn't include the cost of electricity, or the electrical work needed to get the extra 220 volt circuit out to your garage.
