I had a 2015 Optima SXL. No mods except replacing the optima badge off the trunk and replacing it with a Korean K5 badge. Ebony black with chrome wheels. It was a fantastic car. If I had not upgraded to a Stinger, I would have been loathe to trade it in. I originally went to the dealer looking to buy a new K5 GT, but I just didn’t like several things on the K5. I didn’t like the tail lights/trunk area, and the Z for Zorro LED treatment around the headlights. It looked overdone and tacky. The Stinger on the other hand all flows. It’s low, long, and wide, with simple swoopy lines. The LED semi angel eye DRLs are effective yet tastefully done. I’ve been told by several that it looks a lot like a Maserati Ghibli. It looks fast even when it’s parked.
