Anyone who purchased ZZ5 and ZZ383 Deluxe (450/450) is entitled to a $700 US refund as part of the settlement for overstating the hp/tq numbers. I was just talking to the co. handling the process and they are now waiting on GM to transfer the funds to their bank in order to send out the cheques. I let the lady overseeing the process know that any Cdn dealer that I talked to did not know about this. I can post up the contact info for anyone who wants it later when I get home.You need to send down the original purchase docs from the dealer/reseller and sign the waiver form. She had said that I am one of only a few Cdns that has submitted the docs.
