I hear ya on the rear window washer. Our Durango that we had did the same thing, though. Just ran. I'm happy to have one at all.
With my older SX, I've got that ... black plush fabric that all hair sticks to. They are comfy, though. They come far enough under the thighs for Nate, too.
Sometimes I wish I had gotten the newer model, like an 06, because of the analog gauges (rather than my 80's delorean style digital dash), the different seat fabric and the 2.3L. But sometimes I like mine.
I think you may need more time to break in. I've heard of better gas mileage from the 2.3L than that. You won't ever get as good as the 2.0L - especially with AWD, but you should get a bit better. Is that 23mpg on the freeway too?
These cars ARE lowriders! Watch the curbs when turning corners too!
