Last year, after much soul-searching, I decided to trade in my trusty 1998 Toyota Avalon in favor of a smaller, better-for-the-environment car--2009 Toyota Matrix. According to Toyota, the 1998 Avalon gets 19 miles per gallon city and 27 miles per gallon highway, not bad for such a large car. But the Matrix gets 26 miles per gallon city and 32 miles per gallon highway. At the time, there was no such thing as the Cash for Clunkers program that’s available now. My Avalon wouldn’t have been eligible anyway, as it comes in well above the 18 combined mile-per-gallon qualifying mark. Well the program, which is supposed to run from July 1 to November 1, has been such a hit that it has already run out of funding. Congress has just added an additional $2 billion to the nearly depleted $1 billion the program started with.
