I had never heard of them, but apparently they're pretty wide spread and have been around for a while. Like any franchised autobody and paint shop, it depends totally upon the people who work at the particular location.
An example with MAACO, Aerodonamic got a great paint job on his 86SE at the Douglasville store. I took my 87 to them a year or so later and had to make them repaint part of the car before I accepted it. Even with that, I had to take them to court regarding damage and lost items. The paint job had a 5 year warranty and after about 3 years the paint looked like it'd been peppered with small stones across all top surfaces. They blamed it on stone chips, even on the roof and rear deck lid. It was actually caused by buffing compound flakes that had been painted over. They wouldn't repair it.
Many recommend stripping off all the trim like side molding and marker lights, mirrors and rear fascia and engine vents. Remove the tail lights, headlight doors, front and rear lids and remove the wing from the rear lid. Remove all the aero trim including the rocker panels.
Then, do all the prep work yourself or get an experienced friend to help you. You'll get a better paint job.
Here's some reviews of one of the local stores. I couldn't find any for the Albany store.
