Couple weeks ago at a cruise night with my TTA, I had the privilege of having GNX #530 park next to me. Very cool owner, his name is Walter, his GNX has one of the ASC installed moon roofs. Even says ASC right on the moon roof switch. According to the GNX registry its 1 of 7 that came with the moon roofs added in by ASC, not GM. That night was the 2nd time ever seeing a GNX in person, let alone one with a moon roof.
