recently sold my rs4 due to a business venture, will definately be getting back in an rs again soon whether it be an rs6 or rs5 had a look at all the 4x4,s but went for a 535d m sport, find it spot on loads of room and economy is excellent
just cant get used to 4 x 4,s the weight and handling plus you,d probably get a decent px on the x5 at a bm dealer
