Hmmm, you just got me thinking... I wonder if I should upgrade to an STi. I could remove some of the tasty bits I have on my WRX like exhaust, COs, DEFIs, grills and seats and put them in the STi. Then a map from AndyF would bring the perfomance levels back up to what I have now. Trouble is, I'd be going from an 06 to an 07, so not much of a jump and I don't wnat to touch a hatch. Ah! But I have the internals done, so I'd lose that in favour of a stronger 6-speed... hmm swings and roundabouts...
All your cars are lovely, though I'm still thinking I prefer your white WRX (maybe) but great choice for the current car, I'm sure you will put your personal stamp on it soon enough. Sorry for the earlier out-pouring of my thoughts
