another thing with JD Powers - when I had my Land Rover, it was consistently one of the lowest rated vehicles. Yet when looking at the complaints, the number one complaint about Discovery's was gas mileage (same with the Hummer). Hello? The sticker in the window tells you the expected gas mileage before you buy the vehicle. What do you expect when that is what you get? Somehow, I don't find gas mileage a valid complaint when it should be expected to be bad.
(certainly, there are other complaints with LR, but knock on wood, mine was always reliable, just thirsty, which is why I own a Zuk again).
