ok, comin from a previous shop owner... in houston tx...
Exstensive is good, expensive metalworks. Mark who works there used to work at Neckhead and was a good worker. But all places heave their horor stories.
Right now, when I have anyone who wants a bag job done, I use Sean, who works for Lowell Motorsports. Mark and Him both started baggin stuff along time ago, and his price is fair, and his turn around is good.
Mark and I have our personal differences at this time, but he is still good at his job. Just keep in mind, just like at Boyd Coddington.. Just cuz you take it to the good place, dosent mean the best guy is gonna be doing your job.
I would tell you to call sean, see his work. They have a 700+ HP impala there, and a 64 bagged impala that is usually sittin outside.
Call me at 832.722.0396 and i will give you better details.
