is my thought process flawed in thinking that the fuel savings alone will cover the cost.....kinda like getting a new car ( and a $9 lunch once a week) for free???![]()
If all your numbers are correct, you could run a new car for the same price you are paying to run your existing (paid off) vehicle.
I did this 20 years ago when I sold a V8 mustang and bought a new Honda Civic, and gas was $1.xx/gallon back then! (Of course I was driving a lot.) Also factor in how much you don't have to pay to maintain your old vehicle as the new car should be virtually maintenance free for the first couple of years.
