For any hardcore Subarist, S204 is the answer. However, if you have never driven a GC or GD before, then Kitty Cat is acceptable. For those GC or GD owners, Kitty Cat WRX is pretty lame.
My choice would be S204. Also check the original dealer that imported this car. See if import tax were paid accordingly. Many importers disclosed incorrect h.p. and/or car model, hence, paid less tax. This may present problem to you later on.
