They have potential and I think those kits will sell well given the limited exposures those cars get on a national level. (Madhouse Excluded) I think the Next Gen, Gen 6, Gen 7 whatever they are, will do OK, but not on the level of the Monogram kits of the 80s, but then what will. $40 dollar price tags on kits will prevent that. I'm sorry to hear you had a bad experience with customer service. I agree, you shouldn't have to pay for defective parts, but NO ONE cares about Customer Service any more, the only exception seems to be this site's Host!
