Yep, totally agree. Dealers today have more important things to worry about than pissing off a customer over a sd card bought off ebay. The email shown by the OP borders on being a scam email just looking at the wording....."a copy of your receipt"., "name and address of seller........"report to appropriate marketplace"....really? If it was something that important, Mazda would be sending out an official letter on letterhead to customers. No way anyone should worry about this. BTW, NNG is a company based in Hungary......can't imagine having any control over what U.S. Mazda dealers do with their customer's sd cards.
