The Bowers & Wilkins is great but im afraid Jaguar can't make an interior that can handle the power of the system. I brought an XF brand new & every door panel vibrated & rattled when you only had the system on half volume, this & the many many other issues with the car I now dont own the car. I took the hit & got out of Jaguar ownership. I wonder if the seats will be any better than the poorly designed items fitted the the XF
