Patrick texted me the morning of the appt and asked if he could come an hour later, which was fine with me. He was very professional and courteous and let me know some of the ways I could resolve an ongoing problem.
Carlos came early and was easy to contact. Even though I was unable to see him in person (I had a friend meet him with my keys while I was at work), he was very friendly and very specific in telling me what was going on with my car.
Eduardo arrived within the window of time given for the appointment, and checked out the car, itemizing the problem, and getting it started for me. He was courteous and informative throughout his visit.
