The RedSport is a bit of both. It's a gentleman's M3. It's just as explosive as an M3 but without the feeling of constant adrenaline. It's not as refined as Audi s4, but it's more comfortable that both of the aforementioned. I've had over 30 BMW's and when I test drove one after driving the Redsport, the Bimmer felt stiff and uncomfortable. The wind noise and other lack of subtleties … may be a problem for some - especially at the price. Speaking of price, the Redsport is a much better value and Infiniti presents a more reasonable repair option. I like it much better than BMW. M3 is more of a drivers car, but Redsport is more of a complete car. Its a more comfortable driving experience 100% of the time
