I worked for a graphicsagency for a while.
There are cases where you only get a few bucks for your work and you and your client make a deal that you will just take some older unused design that you still had in the drawer and do some modifications to it and call it a day.
I imagine that this might have been one of those cases.
Was probably some really early bland design they made at some point in time and in 2001 they just added necessary stuff to make it a hyundai since that brand was really bland back then anyway and everyone was happy with it.
