I actually kinda like the regular Si sedan...I just don't think Mugen did that car any favors. That spoiler would look much more at home on a Cobalt SS S/C or SRT-4. I've always considered Hondas to be a little too dignified to sport bodywork like this. IMO, the money should've been spent on pulling more horses out of that sweet V-TEC.
I'll also say that I'm VERY surprised at how well the changes I made were received on here. I kinda expected the more opinionated members to gas up their flame guns on the whole MS6 -> Kia Forte subject, but it was actually very nice. That may be because my car lacks the Mugen treatment, but that's just speculation.
What is important is that you like your new car and you feel you made a good choice. If those feelings exist, you did well. I love my new car, and am a bit more relaxed now that I don't have turbo seals, VVT TSBs, and rear diff mounts to worry about.
