what mods can i do to a 2014-2016 panamera to make it look new?

i’m planning on getting a 2014-2016 panamera since it’s decently in my price range and i’m curious on what i can do with it to make it look newer. obviously i know old is old and it isn’t going to look like the brand new ones. but this is essentially my list at the moment

• new radio
• steering wheel
• body kit

let me know if there’s anything more, perhaps if i can maybe fit the rear lightbar. i honestly probably could end up affording the 2017 and get everything but its slightly more limited in modification (or so i’ve heard). please correct me though. thanks.
