I've found the "How much does your commute cost and how do you justify it?" thread very interesting. One thing I've noticed is that a lot of people only have a vague clue as to how much their vehicle actually costs them, and a lot of people were using just the gasoline cost in estimating their commute cost. On my last car, I made a spreadsheet to track all the expenses so I would know how much it *actually* costs me to own and operate a vehicle. It was a real eye opener for me. Anyways, I cleaned up the version of that sheet I'm using for my new (to me) car, added a few calculations for kicks, and have attached it to this post. The current values reflect the early, high cost per mile miles of car ownership (only had the car for 1,700 miles at this point). Replace those values with your own numbers and see where you end up! Enjoy.
