A bit late to the party on this tread, but I cant rate the Passat highly enough.
Ive had two Mk7 (B7?) models now, both with the CR140 engine, one manual and the current one DSG.
I tow 1330kg of Sterling Europa, it swallows the kit in the boot, is comfortable over the distance, and, although im not very experienced towing, hasnt had me worrying about stability etc etc like the old Skoda used to.
I got an aftermarked detachable bar fitted to the latest one, with the car specific loom. Fitted at my house for about £500, all the factory fit funtions work (like cutting out the car fog lamp/parking sensors, alarm detecting the caravan being unplugged and TSP etc)
Reversing camera if you get it is a major boon too - Mrs K no longer has to stand in the 'danger area' directing me to hitch up!
Cheers
