I recently found this site during my used Cayman search and wanted to share. It's the only place I found that generates a free build sheet based on VIN, besides calling the local Porsche dealer. The site is Research My Porsche at Research My Porsche | Porsche. Another good site for checking on lost and stolen and salvage claims is the NICB site at https://www.nicb.org/vincheck. Thanks to both of those sites!
