Because i not only wanted to think green, but to be green also. I have always been a fan of Ford and I wanted a hybrid. the FEH fit the bill, took one out on a test drive, loved it so much that i asked if i could take it on a 24 hr. road test, when i took it back i told them not to sell it cuz i was going to buy it and got it 2 days later. and the rest, shall we say, is history.
