If my Suburban didn't have a broken transmission right now I'd be daily-driving that instead of my Escape that gets double the MPG. And technically I could still be driving it if I wanted to put up with a harsh 1-2 shift and the service engine light being on.
You can see right there, I don't care about MPG. Sure, do I wish the pathetically underpowered Escape did better than 22MPG? Sure, but hey, it's still better than 11.
But you will NEVER hear me complaining about fuel economy, because I am fully aware the vehicles I purchase get poor gas mileage. I am, however, free to complain about gas prices because in this area (California, especially SF Bay Area) gas prices are higher than most places in the US.
If I wanted good fuel economy I would buy a Hybrid. But, I care more about having a larger, boxy-looking vehicle with a comfortable, spacious interior and having a big engine under the hood, than better MPG. And the two vehicles I have, I plan to keep for a LOOOOONG time, so cheap maintenance, easy parts availability, and good reliability is also very important to me.
That said, everybody has different priorities, and if yours is fuel economy, good for you.
