Just pacing the floor-waiting for the 2009s' to hit the lots-hopefully they will have ironed out past problems, rotors, sunroof leaks, etc. My 2000 gmc jimmy has been good, 140000+ miles but only average 17/22 mpg-do a lot of traveling between Daytona and Orlando-starting to add up. thoght I would wait for the new 09 engines-any thought??
