When the Jaguar XK's top is down, the rear seatbelt straps sometimes flutter loudly in the breeze. Otherwise, the XK's al fresco experience is like every other convertible, except this car has a lovely exhaust note that never gets tiring. Top up, there's plenty of wind noise coming off the rear section of the cloth roof, and because the Jag is equipped with a cloth roof it's naturally not as isolating as a retractable hardtop.
