I am about to buy the X5 2005. diesel.But still not so sure if suv or 5 series is better for me. I like the 2 of them. Befor I have Rexton. which use Mecedes cdi engine and never given me any trouble unlike some people in forum who say they got diesel problems. Anybody got X5 or 5 series for the next TT to chat with me? :1:
