I bought this car new in April 2009. It had 6 km on the odometer when I picked it up at the dealer. It has the upgraded stereo, the tech package including heads up display, voice control etc., executive package, comfort package It was amazing tech for 2009, even now it holds up against new cars. Even now the keyless entry is better than what I have seen on all non-bmw cars. I love the way the ambient lighting works and while I used to think a heads up display was a feature, now I would not own a car without it. There is a lot of other tech that used to stand out but over time have just become how a car should be so while I don't notice it on my car, I notice it missing on other cars when I drive them.
The performance has always been great, when the twin turbos kick in it puts a smile on your face. The handling has always been top notch and it goes around corners like it was on rails. This has lead to issues when I drive rental cars as I tend to go faster around corners than they are typically built for.
It has been an extremely reliable car. Other than tires, brake pads, one battery, and oil changes I have never done anything to this car. The all wheel drive handles amazing even under winter conditions.
I originally didn't like the way the signal lights work, but after about an hour they make total sense. I do have one complaint, the cup holders are unnecessarily complicated they way they pop out of the dash. They have never caused a problem, but seem odd.
It can get very good gas mileage if you drive like an old lady. I have done that just to see and I can get to about 9l/100km. The car is way to fun to drive to keep that up so over the 10 years I have owned it I average 12.6l/100 km.
