Here is the one thing you need to realize.
While MAACO is a franchise, their shops are individually owned. The owner sets the standards for who they hire.
I have personally seen a horrible "well, at least it's all the same color" paint job, and a Carlisle show winner paint job from MAACO shops 7 miles away from each other.
The only way to know for sure what you are getting is to ask to see cars they have finished up, check out their booths, and chat with the paint technicians if they are free.
MAACO can be very good, or utter sh*t. It depends on the package you go for, and the shop doing the job.
