It's one of those terms that has changed over the years. The 2012/2013 COPO cars MIGHT have had a fleet sales path, but I doubt it, due to the lack of a VIN#. GM brass authorized their construction, and many/most of the parts are not GM. It even runs a Powerglide.
The original COPO's ended up in hardcore NHRA race teams, but the new ones mostly ended up in private collections.
It's sad that modern race versions of American cars are mostly being snapped up by collectors. On the Z/28, the Serial Number #1 sold for $650,000, and Serial Number #2 sold for $500,000 at auction, with proceeds going to charity. SN 3&4 are being kept for the GM Museum, and a private racer just took delivery of #5 yesterday in Virginia. They aren't being shipped by rail because they are too wide and low. They come in an enclosed trailer that hold 11 units.
I don't even have a VIN# yet, even though I ordered on Day One the allocations were issued. They are only making 500 units for 2014 (the engines and chassis take a long time to build, estimates that only 9 cars per day getting completed).
What is laughable is that few if any late model cars become collectable. The most notable is the Ford GT, which at FIRST was collectible but things might change. Most sold for $50k-$100k over sticker price, yet you can find them at $40k over sticker in cherry condition from collectors pretty easy now.
The ZR-1 Corvette was limited, historically significant (held the 24hr world record for a long time at 199mph average speed?), and started the modern HP war. They are cheap now.
The 2000 Cobra R (they didn't make Cobras in 2000 except the R, and only 300 were built) aren't collectable, yet historically significant due to race victories.
Dittos for the Mustang Boss 302 Laguna Seca (full race, no backseats, low production).
Car collectors are the bane of the enthusiast. They drive the prices up, and availability down, yet they aren't collectable per se.
Luckily, I have friends in GM and got an allocation unit, or a collector would have snapped it up. I'm going to race it, and drive it on the street, or there would no sense in buying one. They AREN'T going to increase in value, because the HP wars are not over yet.
Dodge Jay Leno was the first non-GM employee to drive the Z/28, and it was the one used for the introduction at the Autoshow (NY?), not a production car.
EDIT - Minor correction/clarification. The LS7 427 engine is a mouse motor, SBC. It was designed for the C5.R LeMans/ALMS endurance race cars. GM stopped production of the BBC for all but marine and crate engines many years ago. Last BBC's were put into pickups, Suburbans, and Kodiaks (RIP) and then shut down.
You CAN get A/C and a Stereo as an option in the Z/28; the only option available. Only 8% of the production so far is A/C & Stereo Delete. Which makes me think few are going to be raced.
