Just got my M4 CSL back last Saturday. Looks fantastic. Did full Xpel wrap, Ceramic Pro Gold coat and tint. I, also, had them do my M4 GTS back in 2017. Again, full Xpel wrap with Ceramic Pro Silver coat. CMG has pictures of my CSL and my GTS on their Facebook site.
When I picked up my CSL last Saturday, Dave Salvaggio of Salvaggio Design was there with Kevin Hart's 1987 Buick Grand National GNX. CMG was detailing it. Salvaggio Design fabricates custom cars and has had of several of his cars at Sema (per site below). If CMG is good enough for Salvaggio Design, I think they're good enough for me!

They do, and always have, a great job! Great people, great business and great product. Highly recommend them.
