What Drivers Are Saying About Prothro GMC
"My 2022 GMC Yukon, that I did not purchase from Prothro, was affected by the L87 6.2 engine recall... My grandfather has done business with William Prothro for many years, so I decided to give them a call... By that afternoon the service advisor called me saying they had already diagnosed the issue and it needed a new engine covered under warranty... I would highly recommend Prothro for service on your GM vehicle."

"I found a car I liked online and made the drive from Columbia to Prothro and it was 100% worth it. It really has that family-owned environment and everyone was super welcoming. I got a fantastic offer and really felt like they made the process super easy."
- Kathleen A. (Google Review)
"Hands down the best customer service I have ever had! Unfortunately, my 2018 GMC had an issue while traveling and broke down in Manning, SC, on a Saturday right at about closing time for the dealership. The guys stayed open after hours long enough for me to have my truck and boat towed to the dealership... They supplied me with a loaner for the weekend... All of this was provided to a guy (me) from out of state."
- Allen B. (Google Review)
"Excellent communication about my vehicle order; very transparent pricing; very respectful process from start to finish. I went to other dealerships before Prothro and I got up and walked out, but Prothro won me over."

"Moving from FL to MD and driving my 2011 2500 Silverado, with wife -- 2 large dogs and one cat when we broke down at the motel we were staying at for the night. We had a closing date the following day on our new home... the service manager... Best service I've ever received... had mechanics diagnose it within a half hour... All taken care of and out the door before 11 a.m... by far the best service I've ever received in my 40 years of owning vehicles."

"Over the last 20 years my wife and I have purchased 10 new vehicles from Prothro. I have moved and lived in 3 different states during that time, but always end up coming back for my vehicle needs. Today, I will travel from GA to buy our 11th new vehicle. Don't waste your time at other dealers."

"I don't have enough positive words to express how wonderful Prothro is. My family hit a rogue truck tire on our way to Florida. The tire broke my radiator and condenser. The incredible team at Prothro got my Traverse fixed incredibly fast. They even brought us to a local hotel and treated us with such kindness... the service advisor was simply the best."

"I have been in the auto business most of my life and love doing business with people that I can trust. That is Prothro GMC... I called them and told them what I was looking for. The next morning the salesman called me back and told me he had found one... I bought it sight unseen... Will not go anywhere else."
