Update 7 years later: They're still providing top notch services on my Mercedes cars. The meticulous diagnostics and recommended repairs, plus explanations make me feel comfortable my car is getting only the service and high-quality OEM parts it deserves. Thanks, Adam and GCS team! Adam and Eric run an excellent shop! They always explain the repairs and let me know if something is urgent or not. They're far more affordable and convenient than any of the Benz dealerships around and they do warranty work. The wash and wax before I get it back is great too.
