I know it's not like what you're looking at, but we traded in our SUV for a Toyota Prius last year and we get 2-3 times the gas mileage with little sacrifice. If you often haul around very large things maybe it wouldn't work for you, but there's more room than people expect, and it's nicer than people expect in general. I've had a lot of people comment on both.
If you push the engine hard (a lot of uphill usually) over long distances with the A/C blasting you might get as low as like 45 mpg, if you are on flat ground and don't have to run the A/C hard you can get 50 without trying. If I try to get good gas mileage I can often get 55-60, although that's more difficult at highway speeds.
Anyway, if you put in a lot of miles (especially if gas prices go back up) you can save a lot of gas and money if you can give up a little space.
There's also a larger version of it that has more space and a little lower gas mileage, and a smaller version with a bit better gas mileage, but I haven't tried either.
Assuming ~$2 gas prices, you could fill up the 10 gallon tank probably 2-3 times a month costing like $45-60 as opposed to the mileage range you're looking at which would be over $100 at best (at 45 miles a day). $160 at 17mpg, and if prices go back up the difference becomes larger and larger. At $4/gal you'd save $200+ a month just on gas compared to the 17mpg options.
Like I said it has pretty good leg room, cargo space, etc. and there are some other nice options you can add to it. I'm pretty happy with the upgraded audio system in ours, and the sun roof option is surprisingly nice too.
I wasn't sure we'd use it as much as we do, but fortunately someone put it in when they bought it new so we got to try it for less.
Unless you have to have an SUV, I think it's at least worth a test drive.
Good luck!
