I have known Mark Shackelford for over a decade, and he handled our transaction perfectly. Mark and his team were flawless in communication and have the utmost integrity. Mark has always been a straight shooter, and we are thrilled we chose Mark and Performance Brokerage Services for our sale. I recommend Mark with the highest recommendation possible whether you are buying or selling your dealership. He has been on every side of dealership transactions and performance, and he understands it thoroughly.
