Whether or not it makes sense depends entirely on personal perspective, how much you value having a car that doesn't run on gasoline. If we look at only those costs to which we can easily apply a dollar cost for the average person, it doesn't make economical sense.

The total cost (financing, depreciation, insruance, tax, fuel, maintenance, repairs) of a Honda Civic DX is .50 cents a mile according to edmunds.com. You can visit the site to determine the assumptions they make. That's driving the Civic for 120,000 miles, or 8-10 years, before reaching the cost to buy the Telsa Coupe alone.

The best choices today (from a cost per mile perspective) are easily older used cars with high fuel efficiency. Caviliers, Civics, Metros, etc. If you want to buy a new vehicle which is much more in reach of the average person, and gets great fuel economy, buy a Civic GX.

I read in Automobile the other day that a designer on the Chevy Volt said the car would cost $40,000. GM wants the car to cost $25-30,000 for it to make economic sense for them to build it. Looks like Uncle Same might have to give the tax payer a $10K tax credit. the Civic GX currently has a $4K tax credit
