I thought I'd start an interesting game: First, estimate how long you intend on keeping your car, in terms of years and miles, until you scrap/give it away/purchase a new one. Second, estimate, at a future going rate of between $4-$5 per gallon, how much it will cost you to fuel said vehicle. Third, just for the fun of it, also estimate how much you expect to pay in repairs, maintenance and insurance; basically, everything else excluding fuel. Add it all up and post your approximate total cost of ownership, hypermiling style! We could even compare these figures to those released by JD Powers and other on their estimated cost of ownership. As an example, I'll put down my figures: 1. I expect to keep mine for about 10 years, until a cost-effective electric or carbon-neutral-fueled vehicle is available at a reasonable price, less than $30,000. I drive about 13,000 miles a year, and I currently have about 35,000 on my Odo, so I expect to see around 170,000 miles. 2. At an estimated future cost of gas of $5/gal, and at an estimated 48mpg (rounded down), I expect to pay $13,500 in gas in those coming 10 years. (Thats $5 / 48mpg * 13,000 * 10) 3. I take my car to be serviced every 4.6 months, and that will cost me (inflation adjusted) $3760 over the next 10 years, at a current rate of $75/service. Insurance costs me $150/mo currently, so over the next 10 years that will add up to $18,000. Total cost of ownership over 10 years: $35,260 Now THAT's an eye-opener, but is sure is interesting to consider that with hypermiling, I'll be spending the same amount of money the average driver would use in only 5 years! (according to msn autos and their total cost of ownership data.) Of course, these numbers involve extremes in pessimism and optimism, but I think they are quite well within the ballpark. Who's next?
