All I can say bud. You are a patient man. I don't think that I could car shop...this long. I wish I could be this patient when looking for a new car...I think that I would go crazy.
Well as you know if mommas not happy well nobodies happy...so if she wants the X3...then the X3 it is. I heard the same things about the V8's in the BMW and the 3.0 drinks enough gas and has plenty of power. I will tell you if you truly plan on using BMW's recommended 1 service a year or 10,000 or 12,000 miles plan on adding a little oil. I get mine changed every 6,500 - 7,500 with Amsoil so I don't usually have a problem with this. Keep us posted!
