In this day and age of the internet and social media, automaker communication departments often go to great lengths to keep details of upcoming reveals a secret. It's becoming harder to do so and, sometimes, mistakes happen. This could be one of those instances. A recent eBay listing had something rather unusual up for sale: carbon fiber wheels for the new 2020 Chevrolet Corvette. Thing is, head over to the C8 configurator website and you'll notice no such wheel option exists.

So what was for sale on eBay then? It turns out this set of wheels, described in the listing as "2020 Corvette C8 Carbon Revolution [20/21-inch] Factory Original OEM Wheels Rims Set," could be for the upcoming C8 Z06.

The seller, ertifiedfactorywheelinc, has an impeccable feedback rating from customers, so the chances of them selling fake parts seem rather unlikely though not entirely impossible. Also, why would a reputable seller risk its reputation for faking a set of C8 Z06 wheels? The seller also states "These are General Motors OEM test/validation wheels in excellent condition, with minimal handling marks/blemishes." The wheels were priced at and sold for $4,500 and, taking a closer look at them in the included photos, they do appear to have all of the necessary GM branding and tags.

However, they were manufactured by Carbon Revolution, an Australian wheel manufacturer various OEMs have sourced from years. Ferrari and Ford are also customers.

The staggered set in question are 20- and 21-inches with the name "Carbon Fiber Grey". It's hard to imagine a reputable seller going to such great lengths to fake GM tags simply to take further advantage of all of the C8's popularity. Getting caught would seriously damage its standing.

Plus, these wheels really do look like something from GM's design department and outsourced to a supplier. But the question is how did the seller get a hold of them in the first place? Were they ripped off a test vehicle somewhere? Taken from a warehouse storage facility? It is certainly a bit of a mystery.
