Paulus428i

Hi , I am just about to own my very first BMW which is a 428i Coupe in white and I would like to buy the front splitter , does anyone know where I can buy a copy one from please as i nearly fell over when the main dealer told me it was only available in carbon at £703 ! Also wanted the mirror cappings black but perhaps have them wrapped . If any one has any suggestions that would be great as this is my very first post as a new member . Thanks Paul
