The 3.0 really does suck large amounts of ass. The 2.3 or 2.5 are a little less powerful but return nearly mpg's whereas the 3.0 returns something like low 20's. I didnt think that the model year 2000's had an e85 option but you would certainly see your mileage go down even further. If you still do decide to go with it I would look at the front ball joints. Mine has 14x,xxx miles on it now and still runs like a top...minus replacing the ball joints around 125,000. If you are interested in the v6 i would opt for the 4.0 though. Too bad you cant get a 4x4 with the 4 banger. Somebody correct me if im wrong but the 3.0's did use a timing chain.
