As an E53 owner and Moderator who participated in the design of the new banner and logo, I did lodge my protest

but the idea is to keep with the latest and greatest, presenting an up-to-date representation of current X models, was the decision. Actually, I know that most of the other Admins/Moderators are E53 owners so it's not meant as a slight against the original X5.
Love live the E53!
