i think anyone that buys a midsize sedan with a v8 producing over 400hp is going to be running these cars....and not everyone would waste the trade in, and everythign else on an M5 just to track it, that makes no sense, they are catering to the same buyer.....thoug I think the G8 would be a good alternative a used one of these cars, or even someone that just wants a good performance sedan I finally had a chance to drive the G8 V8 and i have to admit its a good car, the ride and handlign compromise is great, at normal cruising you can hardly even tell you have such a large engine or that much power, its like night and day quiet, comfortable, yet fast and with an awesome sound good car
