Anytime my car needs service, I simply contact Ruby and she handles everything—from getting me scheduled and into a loaner right away to communicating with my warranty company. She makes the entire process easy and stress-free. This is the only place I trust to service my Mercedes, and Ruby is a huge reason why. Highly recommend her!
