I believe that eBay is only liable for VIN tag issues; Trim Tags are body broadcast #s(at the time of assembly) and I dont believe were used to ID a car through any DMV or local PD. However, if a prior car was stolen, if that owner had previously wrote down all the info from all tags, etc; that can be used as an altered ID on a vehicle(where one guys orig tag is on another current car's firewall-good notework and documenting by all of us will help this out but we cant stop the cars that were scrapped from being removed from). It's a sticky grey area that I wouldn't want to pursue with any car or gov't agency! Just my 2 cents...
