There is one main reason Kia is not selling more Stingers or at least as they should be, and that is brand stigma.
People are still convinced that Kia and hyundai are brands that produce unreliable, cheap, terrible cars, and find anyone who spends $40+k on one a total nut job. They percieve the brand as one that you can easily find at any car rental place for cheap and they are correct in that point alone.
Changing peoples perception of the brand is something that Kia/Hyundai have been working on for the past 10 years, maybe even a bit more. Hence why you saw them spending big with ads in the super bowl, also ads on the past world cup, etc. At one point the Japanese were in the same situation as Kia/hyundai are right now, it took them 15+ years to finally convince the north american market that their cars were more reliable and better built than their domestic counter parts.
If you ask me, Kia/Hyundai are doing a hell of a job shutting their competitors up with the vehicles they have coming up, plus no one else in the industry gives 10 year warranty, and its getting them more spot light time, and I think we can all agree it all started with the Stinger.
