I'm in the market for a complete carpet set for a 86 coupe, (graphite). I've looked at the major name sites and $499.99 seems to be the price. Is this about right or are there some other sources that I don't know of that are less but same quality. I'm looking at mass back as my choice. Also recommendations of who to stay away from due to issues as I'm new to the Corvette world. Any and all info would be greatly appreciated. Thanks
