IML: carpet sets

Ok you IMLers. I have yet another question for you all. I have been considering getting my carpet set for from Kanter, and I have heard a number of remarks in all directions on how people on the IML feel about Kanter's carpet. So, in my search for fabric for my car, I found factory original fabrics and factory spec replicated fabrics from an Oregon company. They sent me samples of their fabric and it was a superb match for the original in my car interior. However, the upholstery guy that was going to do my work complained about fabrics that were much thicker than these factory originals and replicated versions telling me that they would never last very long. Anyone out there know how long these original type fabrics can be expected to last with typical wear. Yeah, the car is gonna get driven...that is why I have it, but before I spent $45.00 per yard, I wanna know how long I can expect that investment to last. My second question is this, has anyone out there bought fabric from these guys, and/or the carpet sets that they also make to factory specs? I haven't checked on the carpet set prices, but I will assume that it is more than Kanter. But, if the quality is there, great. The place is called SMS, and I am wondering if you all have dealt with them, and what you thought about either their fabrics or their carpet sets.
