I hadn't thought to check the build date on mine (EX). I just checked, and the build date is June 22, 2020. I bought it on Aug 4 with 6 (my test drive) miles on it.The K5 is fresh. Only around 6000 produced so far. Mine has a build date of July 21, 2020. I've had it for a month. She was fresh off the line.
I'm a car fan, and have watched the K5 for almost a year now. Debut was in S. Korea on Youtube Nov.2019.
Spy shots and speculation before that.
But most don't have any knowledge of it in the U.S. - Doesn't launch in Canada until October.
People actually stop what they're doing to stare at K5.
