My mom had her '80 Buick Riviera painted there, whatever the expensive job was. They did a ****ty job, and destroyed the driver's side door panel. They lost the name badge that went on the trunk.
They had to take the door panel off to take the door handle off to fix some rust, but when putting the panel back on all the Christmas tree fasteners at the bottom were not lined up and they just smashed it with a mallet or something, and broke all the mounts out of the panel where the fasteners go in. I had to take it all apart (they had the trim on wrong around the inside door handle too) and then use screws with trim washers to put the panel on (came out ok, the screws look ok in the carpet section)
The paint itself, prep disaster it was. They they did a **** job taping around everything, and even painted around stuff like the headlight bezel (two screws and its off, painted it anyway). Paint itself has some orange peel, not too bad otherwise. Some of the rust they fixed is starting to come back (been 4 years or so)
My dad had the rust on his bronco fixed there too, (sigh) the regular bronco rust over the rear wheels and tailgate. Paint blending and look was fine and it has not faded, but their rust repair was utter **** and it's coming back now (4 years or so). The tailgate has a big lump of filler on the back of the bottom (looks like they didn't fold the patch over all the way) and they lost some of the screws for the taillight housings. Also messed up the bracket for the tailgate somehow, part of it was ground down for no reason?!?!
As was mentioned, every maaco is different, but they all seem to suck at various levels. You just can't get the level of skill required for the money you're paying. You're paying the rate for a ditch-digger to someone painting cars, so their skills will be of the ditch-digging level plus five minutes of instruction from someone. And don't forget the boss putting them under pressure to get it done faster. There's no way even a good body man could prep the car right in the time allowed.
You'd probably be better off using the $50 paint job techniques and doing it yourself. At least, do the prep yourself, and leave them only to spray the actual paint. At that rate you could probably have a real shop do it because the prep is the expensive part, and get very nice results with good materials at a real shop. Paint prep is not hard, its just time consuming.
