This has been a problem going back to when Hyundai dropped the Azera back in 2006...no advertising back then either. I can count on one hand and have fingers leftover, the number of commercials for the Azera or Cadenza. Hopefully, Kia will move forward with the K8. Not sure what Genesis you've looked at, but when compared to the other premium brands, you get way more for less money. It's sad, the Cadenza/Azera has really been a very nice car.This is sad. If they would have advertised them, even just a little bit, they might have prospered.
I've stayed away from Genesis because you pay more and get less. Fewer features, more cost. That's why I've been loyal to Kia: pay less, get more.
When my Cadenza is ready for replacement, I might still go for a used K900, or Stinger. I'm also tempted by the Alfa Giulia & Stelvio, but the interior features are lacking compared to my Cadenza.
