 I recently traded a 08 BMW m3 sedan for a 2011 S5 and I am thrilled!!While the m3 is a fantastic car, it is not a fantastic everyday car. I made the switch because of the s5's seductive good looks, v8 power, and 4 wheel grip.The s5 interior is stunning visually and very user friendly (BMW Idrive is a mess!)The seats are extremely comfortable and infinitely adjustable.The B&O sound system is fantastic, and would say on par with the best from BMW.Behind the wheel; great steering feel, engine power is substantial but not overwelming. Overall build quality and materials are excellent.My only grips are: the pano roof only vents and the overhead sunglass compartment is tiny!
