There’s an old saying out there: “if you tell the dealers confidential information, consider it published.” But we’ve never seen anything quite like this.

So far, Buick has not formally announced that it even has plans to produce either the Grand National of the faster GNX, but both USPTO filings and our own sources have pointed to the contrary. Adding to the evidence pile is one Buick dealership in North Carolina appearing to be offering spots on a waiting list for both models in a sign that perhaps something is indeed in the pipeline.

“Customers have already started calling about test driving one of these new cars” said Scott McCorkle owner of Liberty Buick GMC in South Charlotte NC. He went on further adding “We are adding their names to a waiting list.” Again, however, Buick is currently mum (officially).

The original Buick Grand National first made its debut in 1982 to commemorate Buick’s involvement in NASCAR racing but did not achieve its most iconic form until 1984 when its all black paint scheme debuted, and 1986 when its turbocharged 3.8-liter V6 was tweaked for more power. The GNX arrived in 1987 (when the Grand National line was on its way out of production) and was modified by McLaren to be a potent farewell to the Grand National thanks to its under-rated “245 horsepower” V6 as well as its limited production of only 567 units. Make note that it was faster than the Corvette at the time in 0-60 acceleration.

In addition to offering a waiting list for the supposed performance variants, McCorkle’s dealership also revealed when it plans to have the first production units on its lot, claiming that the first examples will arrive sometime late next year, and also revealing that both models being based on GM’s Alpha RWD platform. We’ve heard the same.

It will be interesting to see if GM will address Liberty Buick GMC’s bold claims and actions, but the thought of a revived Grand National GNX model sounds compelling to us, and we look forward to hearing more from GM on these models in the near future if they are indeed in the works.

Update: Buick is passing this as a miscommunication of sorts, and the dealer mentioned that the waiting list was based on speculation. However we like to think that this is resulting from the lid opening a little early on the expected Grand National and GNX, and this is routine damage control.
