I gave my fully PPP'ed up Impreza to the wife, as after the 2001 model they became much uglier and with a worse power to weight ratio. Obviously the best was the P1 but they are getting rarer quite rapidly.

The core reason for the Litchfield Forester STi was because they didn't do an Impreza with decent enough performance.
