Sold an Escalade for this SUV. Superfast, Car and driver reviews say 13.40 in the 1/4. Sounds great, spotty build quality with paint and plastic. Great performance, great handling rides like a performance car should, not for the person who wants to ride on an air cushion. Gets a lot of attention at lights and parking lots. Stops on a dime with the huge brakes.
Purchased new early '08 with every option. My 3 year check in-54k miles. 7 brake jobs, odd considering it was 90% highway driving....27 incidents of check engine light coming on-2 pcm's replaced, 2 exhaust manifold gaskets, various cracked pieces of plastic broken while at the dealer while being repaired that will cost a fortune to replace (dealer of course denies). Never driven it rough, never had an accident. Dealer experiences hit and miss, most see unable to address SRT issues and how to fix properly.
Bought almost new (4300 miles) and my wife and I love it! Traded in a 2003 Suburban Z71 and not looking back. Same fuel economy, no third row (we didn't need it), but the SRT8 is easier to park and way more fun to drive. My wife was considering the BMW X5 and the Lexus RX350, but she always had a soft spot for the older Grand Cherokees. I pointed out the SRT8 had better seats and better performance than the X5 (she's an aggressive driver for a girl :) and she didn't believe me. One test drive and she was hooked. I wasn't looking forward to driving a minivanish Lexus or even the more performance Bimmer (and I own a 540i.) But this is truly a vehicle that both of us love driving!
In spite of a few reliability issues (e.g., occasional erratic A/C and occasional erratic power), this car is built like a tank and accelerates 0 to 60 in about 4.8 s! For a 5,000 lb SUV for less than $50k, this is fantastic. It also handles well and is less prone to roll over than many other SUVs. And, it looks good too. I would not hesitate buying another.
All I can say is that this Jeep is not what I thought it to be. First off, when you punch the gas, the Jeep has this big delay and hesitation. Then it will take off, by that time the other guy is at least 3 car lengths a head of you. I just don't get it. This truck is to have 420 pony's. But it feels like it has half that. Its said to say this but Jeep needs to re-think things a little. I still have my 01 X5 4.4i. And I had my buddy race me with it, sure enough my old X5 beat me by a car length. I'm tellin you, they just don't build them like they used too. Even BMW has changed there stuff. I'm getting rid of this truck and picking up a Porsche Pepper. That turbo S is sick.
