New member here, currently an e39 Dinan 540 owner. Soon to be x5 owner. I was given a referral from the guys over at bimmerforums to ge on here with all my questions that no one seemed to know. So here I am, as soon as my e39 is gone I will be purchasing an x5. Most likely a 4.6is, but I'm still debating the option to just go with a 4.4. Anyhow, I just thought I would drop in and introduce myself first. Any advice on what to look for or opinions on whether I should go with either the 4.6 or 4.4 are defenitely welcome. Thanks guys!
