Many thanks.
I only know of shop via a colleague who is extremely pleased with quality of their work on his GT R Pro and his 2 other AMGs.
Another very quality shop I have personal experience with (between LA and Fresno) is:
https://europeanperformanceautomotive.com/ in Bakersfield (only 30 minutes from Buttonwillow Race Track)
Mark was former MB Master Technician, and has outstanding knowledge depth and detail.
He definitely has my repeat business.



My bad.
