Interesting . . . I was guessing that GMBuyPower was coordinated by the General - not the individual dealers. Why wouldn't a dealer participate?
When I found my Av on GMBuyPower and called the dealer, the salesman had a hard time finding it. It was not yet in their sales floor records - it was too new - still in transit - not yet on the dealers lot. We bought it sight unseen, and drove it home within 2 hours after it came off of the transporter.
