John Felstead's STI V5 RA you posted the link to is almost the perfect fast road spec. I was at the rolling road day (that's actually my picture) and it was what I'd call the perfect impreza.
I'd deffinately buy it if I had the spare money as it's a really nice spec with the closed deck block and associated engine parts plus great suspension setup.
Although it's a 4 door being an STI RA it still has the DCCD like the type R, also has a decent low ratio box with a longer 5th gear than the earlier RA's.
Superb car!
