I agree with all of the above. I have two friend's who've had their cars painted at MAACO and one has been featured in 3 magazines. The other one is also show quality and it wouldn't surprise me if it were featured at some point. I also know of another car (a '74 Chevy Vega) where the owner did all of the bodywork and took it to MAACO. The job they did turned out to win him a lot of "Best Paint" awards at many major shows. It's all in the prep work and the quality of the paint. If you choose their cheapest paint job, it'll chip and flake. If you choose their most expensive job, it'll look awesome.
Regardless of who you hire, you'll save a lot of money if you remove all of the emblems, decals, hardware (antennas, door handles, lights, weatherstripping, etc...) This work is something that anyone can do and it leaves the professional to do what he's really trained to do - work on the actual bodywork and paint.
