Mine is 2007 4.8i. Now it has 43K miles. Basically very reliable vehicle. I agree with previous post about rough transmission, but you just have to get used to it and know how to drive it. If my wife does it smoothly - anybody can do it . Also, agree that Idrive system could be better, but even 2011 Idrive is not user friendly IMO compared to my 2010 E-class Mercedes Command system. Gas mileage sucks, but if you wanna have a power - you have to pay for it, otherwise buy KIA . I think if you wanna have powerful SUV and don't wanna spent a lot of money for brand new - 2007-2008 model, which is still on factory warranty for sometime is very wise choice. Good luck.
