I would still think though that a shop would make a profit out of out it. Maybe only doings coupes. I've never actually seen the production process but I do realize its quite difficult. I don't know a lot about it only what I've read..........But Out of all the Z owners out there looking for things just like this to take their Z to the next level it would have to make a profit for the shop. I know there would be enough interest.........it might be a while before a profit was made but I think the money would be there eventually. thought?
