so lets see.
30 grand for new car, saving $20 per full tank of gas, will cost you 1500 fillups.
assuming so guessing you get 700 miles per tank, that means you must surpass 1050000 miles just to make back your initial investment.
but then id guess you did prolly get 16 grand for trade in, so you only lost 14 grand, or you need to do 700 fill ups, or 490000 miles
note, i think my math, guestimates are WAY the hell off. something isnt right.
Assuming it's averaging 55.5 mpg versus the original's 17.5, assume the price of gas hovers around $2.50, you just linearize it an solve: 2.5*x/55.5 + 30,000 = 2.5*x/17.5 -> x = 306,710.5 miles to pay for itself. Assuming you drop it from 30,000 to 14,000, it solves to x = 143131.6 miles to pay for itself. If the price stays at something more like $3/gallon, you're looking at 255,592.1 miles for $30k or 119,276.3 miles for $14k
So 10 years at average (12k miles/year) driving rate? SWEET!
dont forget the battery replacement cost, which is $$$$$$$ say bye bye to gas savings!!
