I have a set of OE Passat Carolina Wheels (16x6.5, ET44). They are shiny, but each have some scratches, so it sound like these aren't the right ones for you.
Your car takes any 5x112 BCD wheel, and these are fairly common on FB marketplace and Craigslist, but a bit harder to find in new take-off condition. I think the Passat wheels are also often a bit wider than the others, which may/may not matter to you. The newer cars do not use TPS sensors (tire pressure is measured by rotations), and most often older wheels do not come with sensors, so keep that in mind for pricing. The pricing varies widely, maybe $100 a wheel for a common 16" in GC, to easily over $1,000 for 18" special edition wheels. The salvage yard also have lots of take-offs, but finding them in GC is a challenge.
