Hi V8, I've never seen that site before. Is it eBay transactions only? Great site! Many of the submissions in the Buyer & Seller Rating Guide were submitted by Z owners who purchased or sold items with other Z owners or Z specific businesses, either through Z sites, chat rooms, message boards or Online Classifieds. It also has ratings for several Z mechanics and repair shops. And there are eBay based reports too. It provides additional IDs beyond eBay like email addresses and names, when available.
