The smug is a huge reason not to get one.

I have a gas guzzler (that I adore, except for the mileage) and my circumstances have changed since I bought it. I'm driving more (450 miles per week), we're getting rid of the boat we needed to tow, gas prices have gone up, etc. That doesn't change the fact that I have a car payment to make, and unless I can get a return on the investment I made in my current vehicle, buying some new hybrid is the least sensible choice. In fact, even with the increased gas prices, I'm paying less on my current vehicle than I would for a hybrid.
