Hi People,i am a new member and i am here to ask your honest opinions on the the lovely X5,I have a bit of a dilemer that i think you guys and girls could help with. I own a Lexus RX400h (hybryd) and while its been an utterly reliable family car for me i have recently bought a 25ft caravan which it tows with ease but i only get 18 MPG when towing,so the question is ??????? If i buy a BMW X5 3.0d auto would the economy be a lot better or about the same,i really like the X5 and cant realy see an alternative,i just thought i would run it past you guys as you use them everyday. Many Thanks Pete.
