Front bumper sold for $200. I now have the OEM M rear bumper ($200 from an auto salvage place in Houston)

and the diffuser from a forum member. $100 more in parts and pieces and then $500 for prep, prime, paint and install and the rear and front will be a complete set. This is more for resale value and my overly-needy desire to have the same trim level on front and rear than it is for looks.
