I love mine. Had it about a couple weeks. Light Khaki Metallic 4X2 SXT base model. I haven't really checked the mileage but every vehical I've ever had averaged in about 2 or 3 miles per gallon more than the city rating after it was broken in. I've never had a vehical do big freeway numbers (but then I guess I don't do a lot of freeway driving...lol!) That would be about 20-21 mpg average on a new Nitro and that's great for me! Anything that big that looks that cool I'll be very happy with 20!!! Great overall vehical so far. I really see the German influence creeping into the line and I've had a Benz before.
