It's like the new edition of the coveted 22B STI. 
That's right. The P25 was a limited run of 25 brand new cars built by Subaru in consultation with ProDrive. Hence there are subtle changes to the original 22B's basic design. The lucky owners of these cars had to stump up over $550,000GBP depending on options. For their money they got a car prepared to the same level as a Singer Porsche or Alfaholics Alfa. And it is an animal...a barely street-legal race car that will scare the living crap out of you!
