Kimberly,
I've had mine now for about 4 months, traded in a 2017 Mercedes C63 AMG S, while I thought I was downscaling, I find that I really upscaled, except for the fact that the Mercedes had 500+ horsepower. My GT2 has more features than the Mercedes and it is more fun to drive. My Stinger has also soured me on Mercedes knowing how much more Mercedes could have given me for what I paid, but didn't and chose to price gouge.
That said, I feel you are right, the Kia name brings different feelings to each person who hears it. For me, being 50, I initially thought lesser quality than Toyota\Honda but basically reliable as they must be doing something right to offer a 10 year / 100,000 mile warranty. Since buying one, a rumor I have heard is that the Stinger and Telluride were supposed to mark the beginning of a new line for Kia, creating a more luxury line, like Hyundai --> Genesis, Toyota --> Lexus, etc. When I got it, one of the first things I did was rebadge it. Since then, people have asked if it was a Maserati, Jaguar, Porsche, etc. It is kind of fun to say "No it's a KIA", most people are blown away when I say that.
