KIA USA should take at least half of the KDM Stingers they got and put them in shopping malls around the country. It's possible they started doing this already but they need to do it more to show non enthusiasts the car.
KIA USA needs to advertise. I don't watch a lot of tv but I haven't seen one commercial on the car. Newspaper and non-car magazine ads would be nice too. Keep the hamsters out of any Stinger commercials.
Have a Stinger on display at car racing and car show venues for people to check it out.
All of this has been done before with other manufacturers so it's not that difficult. They just have to do it.
The question I have is, how many Stingers is KIA planning to sell in the USA? Are they gonna sell as many as they can build or will it be like the Chevy SS was in the US where they may only plan to sell 500 or 1000 (or whatever many) per year. If KIA is only planning on selling a few hundred a year, they may feel they'll sell all of them with just minimal advertising and then let the cars speak for themselves as people see them on the street. But if they plan on selling high volumes of them here then they're going to have A LOT of them not moving on lots with that strategy. Enthusiasts like us will buy them but the average Joe won't know what they're looking at or that it even exists in the first place.
