I had always lusted after the Civic Si back when the 2000's were new. Once Honda went back to the hatch-style I moved on to other cars since it didn't fit my life. As soon as the new "Si Sedan" came out I knew what my next car would be. I purchased my 09' in June and have loved every second of it. This has got to be one of the funnest daily drivers out there, despite requiring premium gas I am still getting upwards of 26+MPG with very aggressive driving. The seats are a magnet for cat hair so I am going to need to upgrade these to leather soon :-) I have also (Eibach) dropped my car about 1.4" in front and back and the handling is much improved.
iVtech putting out 197 HP and getting 26 MPG is excellent :) Some are getting 400+ WHP with about $3k bolt-ons.
Perhaps add more "Si-specific" styling to differentiate from the Vanilla Civis
