I come from many years back - probably the oldest Stinger fan on this forum. As I posted elsewhere, in my early car days, there was a "sleeper" fad. We stuffed huge engines into plain-Jane cars, or took all the ID off our cars (I turned my '70 Plymouth GTX into a "Belvedere"). It wasn't a de-badging because cars were easily identified, but rather an attempt to hide whatch' got under the hood. So racing stripes were only seen on little sports cars like the Triumphs, MG's and other 2-seater sports cars.
What I like about the Stinger is -- well, it's a Kia. None have been seen on the streets in my part of the U.S. and the Camaro and Mustang drivers don't (yet) have a clue what they are -- just a Kia. Putting racing stripes on "just a Kia" is sort-of a joke...at least for the time-being.
Mine is another month or more away (unless the dealer finds one in the woods somewhere), and I'm going to have fun until the "new" wears off and people begin to respect the Stinger. For me, that means no stripes. The wheels are "bad" enough to mark it as something -- well, special.
