Like was said above, watch out for the front ends. Get the dealer to replace the ball joints if they are loose.

In 00 the 5.2 was replaced with the 4.7. They also got a new trans at that time. I havn't had any problems with mine in the two years I've owned it. I've gotten a best of 18mpg with my 4.7 however it's usually in the mid 15's.
