I have a 35 mile commute each way to work which I had been doing 5 days a week. I decided to buy another car since the one I currently owned had 192,000 miles on it and didn't get very good gas mileage. I bought a Scion (not the ugly boxy one) which gets 35 mpg and didn't cost lots of money, plus the dealer gave me $1000 for my old car. I was also able to reduce the days I drive to work to 3 instead of 5, so I now drive 560 miles less every month and have to fill up only every 10 days instead of every 4.
