Just a quick shot with my little copilot in tow. 2016 S550W4, Executive Rear Seat Package Plus. Love everything about this car, except the base 18” wheels. Noise and ride quality great, would appreciate the look of multi spoke. Is it as simple as ordering and replacing rims a designed to fit? I found some higher quality runs modeled after the OEM that my neighbor (MB Master Tech certified) has used. Thoughts?
