It's been said before, but we Optima owners just don't want to give up some key things we enjoy now, like cooled seats, 360-degree camera, wireless phone charger, etc., etc. Kia should make the Stinger a clear upgrade path from the Optima, but by deleting features, it makes it fuzzy.
Believe it or not, Kia, not all of us want to generate huge clouds of tire smoke and drive sideways at 4 G's. True GT cars should be dripping with creature comforts, not just raw power. Grand touring means the ability to cover large distances in comfort and quickly.
