I'm looking for a mid-size estate for general motorway use, but also for outdoor gear and to carry kayaks on the roof - perhaps even to sleep in the back with the seats down (I'm six feet tall). I've narrowed it down to these three. I'm keen on the 2.0-litre diesels from around 2005-2007, and my budget is £6000. I'm erring towards the Volkswagen Passat as I think the Volvo V50 is too small and the V70 not a fun enough drive. I've also considered the Audi A6 and Mondeo, but feel the first has not enough mpg, and the second is not pretty enough. It will probably end up as my fiancee's main car.
