I guess money isn't an issue at this point? You're kind of all over the place. Sedan, SUV, performance, hybrid.
If you are sticking with SUVs, it's hard to argue with the X6M/X5M. If she likes Benz, go check out the ML63 AMG as that is 4Matic AWD. However, take a look at the Porsche Cayenne Turbo or GTS, and if she wants to save a few bucks, I highly recommend the Jeep Grand Cherokee SRT-8.
