Back seat luxury

I currently own a BMW 320d, and am planning to upgrade. I am considering the BMW 525, E 250 CDI, A6 2.0 TDI and Jaguar XF 2.2D. The car will be chauffeur-driven. Which do you suggest?

AAA If you are going to be largely chauffeur-driven, then the E-class is your best bet. It has the best back seat of all and offers a good view outside for rear-seat passengers, which subtly adds to overall comfort. Also the E250 CDI with its twin-scroll turbo has punchy performance but it is slightly noisier than the other cars. The ride quality of the E-class is pretty good too.
