Last I heard, Hyundai Motor America said that not all dealers will sell the new Genesis branded vehicles. Only about half of the dealers now sell the Equus, so it might something similar to that, but that is just a guess.
3 of the 4 dealerships here have a total of 5 Equus' on the lot according to their online sites (4 black and 1 white FWIW). It will be interesting to see how it all unfolds. Hopefully us current owners don't get lost in the shuffle.
