My 6/00 build 3.0 kind of is loud with wind noise on the freeway, and sometimes its kind of loud on surface streets. I know that big cars(SAV) make more noise because its more car cutting through the air. But, isnt that low drag coefficient suppose to help. How much noise do you guys have at city speeds and highway speeds. I also would like to know what you guys did to reduce or eliminate wind noise if you had this problem. I am asking because I really dont know how much noise the X5 should be making from wind, right now its pretty loud. Thanks. All input is greatly appreciated.
