I want an '06 for the updated interior, but that engine would shove the price up above what I can afford. Trust me, if I could afford it I'd have one already.
Then just admit to yourself that you've misplaced your man-card and buy a Prius with a bicycle rack strapped to the back. That's what you really want, you just can't bring yourself to say it.
My WRX also averages 23 MPG, and I've been driving it for two years. It also requires premium fuel. I'd rather be in something that I am completely comfortable in, and it would also mean I can go from having a DD car and a truck for hauling the ATV, to having a single vehicle.
BTW, the '06+ HEMI's have displacement on demand. Whatever slight mileage difference there may be between that and the WRX is made up for by the fact that it's also 20 cents a gallon cheaper.
