Just to note, the twin turbo legacy's seem to be much easier to insure than a WRX or STI.
Have one myself, great all rounder car in my opinion, big comfy car and loads of power if needed, 280BHP manual and 260BHP tiptronic. Loads of bottom end power with the sequential set up, and a good kick up the arse when the two turbos spool.
This my first subaru and I will be getting a blob WRX or STI next, but as I said, great place to start.
