I have a 2015 K900, and I'm very happy with it. In fact, I traded in my 2013 Azera (the Hyundai version of the Cadenza) when I bought it. For whatever reason, there is no K900 forum here. If you want more feedback regarding the K900, you should try posting on K900forum.com. You'll find a small but relatively active group of K900 owners there.
