i have had experience with mac, they are within high standards, from the shop to the tools and down to the people working there.
if i were you, id take a trip down there and youll know what im talking about.
i havent done any major mods on my car but had my bumper redone from them and it was perfect.
if you take some time and look at the MAC thread you'll know what im talking about.
its competition who does a perfect job, there will always be other places.etc
only a few really get to the point where they are highly reputable.
