You should talk about the exelent combination of sport and luxury.
In a BMW (3 and 5 series) you can confortably cruise (glide) down the street with a confortable ride and engine prrring like a kitten. But when you need it with just a press on a pedal it instantly converts int a beast that grips the road like a cat handles in corners like crazy and the roar from the engine ........
Speed never killed anyone, its the sudden stops that hurt!!!
