I'm new to the forum and just took ownership of a brand NEW 2007 Grand Jeep Cherokee Overland Hemi...First off, this is one fine ride...POWER! Lot's of it when needed, second, it has every option you can get. I have been a Mercedes guy for the past couple of years and decided to look at the new Hemi jeeps. Well, I'm glad I did because this absolutly blows away every part of the ML 500 Mercedes...I do not know were to begin however, the new 2007 HEMI is PUMPED UP!...Now, for the fun stuff, add on's...Jet Chip, K & N Air tube...Headers when the become avalible. This rig rocks.
