Well, driving at the limits is "fun"; so is being able to control the car.
Sometimes driving an unrefined car (A Mustang, an MG, a kit car, a 240Z) can make you smile just as big as driving an expensive/refined car.
Sure the systems in a 370Z are highly refined, engineered, tested, perfect, BUT sometimes it's great to smell fuel, have trouble unreeling the seat belts, having a dead mechanical clock in the dash and clunk sounds in the drive line.
