I drive 10,000 miles per year, the average cost of premium is $4.40, and similar luxury cars (Mercedes, BMW, Audi) get about 20mpg. That is $183/mo in gas ($4.40/gal * 833 mi/mo / 20mpg) I won't have to spend. Subtract the $30 or so in electricity I will have to spend, and I save $153.
right but the monthly payments, which is what they are advertising, is still $153 greater. Advertising the opportunity cost rather than just the cost is very misleading.
