"Where did you get the VIN's that are listed?
The sources for the registry are numerous. Many owners have submitted their information to me. Cars that are listed on eBay, Cars.com, and AutoTrader.com are included if the listings contain enough information to be meaningful. Anonymous sources, presumably from AoA or their dealer network, have sent me information. Individual dealers have contacted me regarding cars that have passed through their dealerships. Sometimes, people spot RS4's parked somewhere, write down VIN numbers and car information and send it to me."
