Drove to AZ from CO this past week, and enjoyed a whopping 12 miles per gallon on the way out! When I reset the trip computer before we left, I was at 13.5 which is 95% city driving, so my 800 mile trip actually decreased my gas mileage! Now, it was cold out, we drove through the night, there was a very strong wind which was never behind us, and the XK was loaded including 2 suitcases on the roof, but still not what I was hoping to see. But with gas being ~$1.50/gallon, it makes the sting of 12 mpg much easier to stomach. I got 13.4 on the way home. I was going to take photos of the XK at the gas stations on the way back, but it was way too cold.
