Both cars are awesome. I simply chose the Speed 3 b/c of attractive dealer incentives in Canada. Otherwise, I would be riding in the SI right about now. Anyone would look great sitting in the drivers seat of either one. This thread is biased to the max.
I wouldn't say this thread is bias at all. To even be comparing the Civic si to the MS3 is ridiculous! The MS3 is way way faster and a better value period. I've owned both I know this.
