Since its inception in the US in 2014, Kia has only sold approx. 4,500 units thru' Sept'16. To give this context, Toyota sold about 430,000 Camrys per month.
For the past 4 mos, I've only had 4 sightings of this car and I live in a major metropolis.
I submit that K900 sales will slow to no more than a handful per month unless Kia dedicates a separate badge and dealership network like what Hyundai has done w/ Genesis, or Toyota w/ Lexus, Nissan w/ Infiniti... You get the idea. When I pulled the car in for an oil change, yes, I got soft glove treatment, free loaners etc. The service guys were nice and the work was done to my satisfaction. But the customer waiting area is a spartan room w/ a few chairs and a TV; not even free bottled water and don't mention coffee/soft drinks. You sit w/ Soul/Forte owners (now, I know this comes across as pompous but when one pays >$60k for a premium sedan there are some expectations here) who weren't expecting much more. The contrast was huge as the following week we took the Honda to the shop for its oil change. Service customers share the same facilities in the new car showroom with workstations, dedicated children play area etc.
Of course, hind sight's 20/20 and I'd admit this is armchair qtr-backing. Kia made the wrong decision to plaster the KIA logo all over the car. Even if it chooses to forego the $$ needed to build a new brand, it should have at a minimum replaced the US KIA logo with the Korean "K" design like what the guy at the Optima store is selling.
It's really a string of bad business decisions that is hurting the K900, which otherwise is a truly fabulous car. 90% of an S-class at 55% of the price with at par if not better reliability and a much better warranty.
