Another service and repair for one of our Chevy’s. Eddie was great at communicating with us. The car was not done on the day promised but we pivoted and made it work. The pick up process continues Eddie was great at communicating with us. The car was not done on the day promised but we pivoted and made it work. The pick up process continues to be frustrating. I have complained many times and nothing changes. SUPER frustrating. It took almost 40 minutes to get the car. They park it at the GMC dealer across the street in the parking garage even though I said I was coming that day to pick it up. A service guy has to saunter (they walk slowly) from one dealership to the other one and get in the car and drive it back over. A very inefficient process! Change it! Sick of complaining about it and about waiting for a car. More
