when I bought my 07 GC hemi, I didnīt read ANYTHING I didnīt even know it had a 5.7, the dealer told me when he was driving it and explained me the engines, I said whatīs a 5.7 good for?? and he pushed the pedal to the metal, and it was instant love (I even had to tell him to stop!! haha); I didnīt even care that it had a non starting issue.
Anyway I may add somethings to check before buying a GC HEMI,
First: I can only speak about the 5.7: check that the jeep you are buying starts right up with a beasty engine sound (no delays, or lazy start, or too much clanging). Mine didnīt!!! even some times, it didnīt want to start at all, completely dead for 10 minutes, so I took it to the jeep doctor and they said it didnīt have the right battery, and also the starter was wearing out its bushes so they replaced them, and problem solved.
Second: itīs a permanent all wheel drive, with a 5.7 engine... that is no cheap on gas on any scenario!! on city, starting and stopping that 2 ton beast every 3 to 5 minutes means a lot of gas. Yes, on highway (actually at CONSTANT speed or cruise speed) it stops 4 valves, and works on 4 valves, but that does not mean it will drink half of your gas!. If you are on a tight budget for gas, look somewhere else, because this is not a gas economic 2WD car. Still, my 2007 drinks and spends almost exactly the same amount of gas than my fathers 2011 Cherokee (ex liberty) with a 3.7 engine, in the year 2012 when we compared them.
Third: check the 4-lo speed (put your foot on the brake, get it on neutral, and lift that little chrome piece of plastic on the extreme right of the D (direct). It has to make some electric noise like a small electric engine moving some clogs, and thatīs it! move the jeep a little to check if it works, and you will have the 4LO light on the cluster. Beware that this is only for non hard terrains, using it on hard pavement can make you have an accident because the wheels turn at the same speed (itīs the axle blocker).
Fourth: it has a MANUMATIC shifter that can help you (check if it works properly): it has a "-" and a "+" sign, to control the MAXIMUM gear the jeep can engage. For example, you need more power for a short period and donīt want the jeep to loose it going to a high gear like 4th or 5th, like when you are passing another car or truck. You move the gear to the "-" and on the cluster, next to the speedometer it will show instead of D a 4. Move it again and it will show a 3, and so. After you do your business, you can release it going to the + and you will see the numbers increasing everytime you move it or just stay it on that position for 2 seconds. You will find that this is extremely helpful not only at high speeds, but going offroad at low speeds also.
2005 have poor plastic door handles (inside), but it can be fixed with a door handle solution from ebay.
Note that the 2008 model has a cosmetic upgrade (bumper, lights and grill are "different", with the fog lights in lower position, making it look a little bit more asian style for my taste), the 2009 has an engine upgrade (VVT or variable valve timing giving it a whooping 27 hp increase, YAY!!), and 2010 was the last version of the WK GC. Also note that the SRT-8 version is just for street, not for offroad purposes at all; the suspension is a couple of inches lower and it does not have locking differential (4LO), also the transmission is made for high speed, and the exhaust gives its full hp at higher RPMs, while the normal version makes the opposite (it has short exhaust manifold that gives high power at low RPMs). Overland version has 18" and 7.5" wide rims, all rest have the same but 17". Also the overland version is the one with REAL leather instead of vinyl leather. For the 2009 and 2010 models, you can find overland seats in different color than brown. The export edition is WH (europe and australia, donīt know if canada). Many parts are shared with the Jeep commander.
You can lift a GC 2 to 3 inches without compromising anything, with budget hard metal separators or with suspension exchange (higher coils and struts from the OME lift kit). More than that is not recommendable because you alter the geometry of the car, and you will need a part to tell the computer that.
Other than that, I will not change my car for anything other than a better GC.
