As of the "update" from the 4000 guys forum, there are 44 cars currently registered. This total doesn't include the Audi Club cars, so for sure that number is higher. I for one am going and I know a few other V8's that are as well (other than Ron W). Depending on timing I may bring both cars. Scott '90 V8 Quattro Papyrus Metallic '90 V8 Quattro Pearl
