How many Nero Challenge Stradales?

Go to the CS registry and start counting. Then double that number to get an idea. I did that for my Argento Nurburgring / red and black interior recently and came up with 3 in the registry. Since the registry has about half the production accounted for, I figured there are probably another three out there somewhere.

Looks great in Nero I say

 

Nero or Nero Daytona? North American or worldwide??

Interesting formula... lol In NA alone, there are 22+ Argento Nurburgring CS' and at least 9 with your configuration of Argento Nurburgring / red and black.

 

Right now, there are 5 US spec Argento Nürburgring with red-black alcantara cars in the public VIN database:
Challenge-Stradale.com - Ferrari 360 CS VIN 135087
Challenge-Stradale.com - Ferrari 360 CS VIN 136866
Challenge-Stradale.com - Ferrari 360 CS VIN 137363
Challenge-Stradale.com - Ferrari 360 CS VIN 138100
Challenge-Stradale.com - Ferrari 360 CS VIN 139598

I do have 4 more US VIN's with Argento Nürburgring and red-black interior but not allowed to share these at the moment. So that's at least 9 US spec cars in your configuration like Stokpro said.

And here are another 5 cars in Argento Nürburgring / red-black alcantara in the rest of the world:
Challenge-Stradale.com - Ferrari 360 CS VIN 135093
Challenge-Stradale.com - Ferrari 360 CS VIN 137044
Challenge-Stradale.com - Ferrari 360 CS VIN 137377
Challenge-Stradale.com - Ferrari 360 CS VIN 137869
Challenge-Stradale.com - Ferrari 360 CS VIN 139357

So at least 14 cars in your config in total (worldwide).

 

Now the black cars. Here are some statistics about the CS VIN registry:
Challenge-Stradale.com - Ferrari 360 CS VIN Registry Statistics

Nero 27 (4.23%)
Black (Nero or Nero Daytona?) 23 (3.60%)
Nero Daytona 13 (2.03%)

In total 63 black cars (worldwide). This is 9.86% of the 639 cars in the public registry.

 

I was just going down the roster looking at the color icons and that's what I came up with. I stand corrected.

 

Here in Brazil, we have 8 CS's. 7 in rosso corsa, and one in Nero with red leather interior.

I don't think that any of them have factory stripes.

 

Here's the Nero Stradale with red leather in Brazil:

Recently, I've found pics of a different looking black car in San Paulo on Autogespot:
Ferrari Challenge Stradale - 11 november 2015 - Autogespot

Do you know if it's the same car? There are a couple of differences (rear wing, yellow calipers vs aluminium calipers, black racing harnas vs normal seatbelts).
