You could get it from the dealership. It looks just like the Optima SXL badge. Although they decided to do away with specifically branding each model on the Cadenza.
Thank you for the information Will.
Do you have the K badges in faux carbon fiber (7 set) for the Cadenza yet?
I didn't see them on your site.
Not to "butt-in" on Will...but yes, he tells me that he does have them. I'm not sure if they're the same price, but PM him and he can tell you. I'm interested in them, too, so if he gives you a price would you mind passing it along?
