Not bad, there has to be a way to lighten it up a bit more without sacrificing saftey and quality. If your not gonna use a rear seat maybe you could cut the pan halves out and replace them with fiberglass ones, and even the rear luggage compartment ( fire wall, etc.). VW Innovations (Glass Action) sells them. I dont really know how well that would work but its an idea. They said the pans bolt in, you could just use fiberglass resin or bondo to seal and smooth them out.......
