Puzzle for February 5, 2010

I bought a 2006 Diesel VW Jetta Wagon (TDI) in (the last week of) May 2006. I drive it on the highway to Roswell, NM and back (408 miles each way) and around town. So far, I have 140,000 miles on it already! How many miles do I drive a week (on average)? How often do I go to Roswell?

And the more important question, if I'm getting 50 miles to the gallon of diesel and it costs (on average) $2.59, how much have I spent on fuel so far?
