It's not a 22B, Prodrive are not chopping up 22B's to make P25s. Its inspired by the 22B.
22B's are selling for crazy money today, the highest auction price to date was £480,500, this was McRae's car.
I remember back in the early 2000's these were coming intro NZ as used imports, they could be bought for 30/40k NZD. There was one for sale in NZ last year which the owner wanted 600k NZD for.
