The guys at M&M are my heroes. I brought my beloved 2004 Corolla to them because the air conditioning was working only intermittently. I was expecting a very large bill (because I had paid big bucks in 2009 for an AC repair at the dealership). To my surprise, the M&M guys were able to repair my AC for a small fraction of what I paid at the dealership.
The M&M guys have integrity, and they do good work.
