The only thing I ever regret is the slightly heavier curb weight in the rear. However, that's still not enough to sway me. I love the coupe. I love the look (with the HFP kit) of how aggressive it is.
I love the large doors.
I love the grille more.
I love the large windows.
I love the silhouette.
I love the 3/4 angle where it looks bunched up and just...meaty.
I love it because Dawn has one.
I don't bring people with me a lot, so the two extra doors make no sense.
I hate leaving too much stuff in the back seats (I only have my sunshade and a hat there) because it gets way too cluttery -- having a back door will exacerbate this because it's easy to access.
I always open the trunk for my backpack.
I have no kids.
I have no inclination for the JDM/CDM/Mugen front look (well, maybe the Dominator...)
I do not mind waiting for people to get in the back, because they HAVE to go through the passenger door, my seat always stays where I want it.
I love the aggressive front face.
I love the lackluster back end (though I do really like the Sedan rear more)
I do not like the front face of the Sedan. I do not like the slightly higher seating position. I do not like the door garnish compared to the coupe. I do not like the slightly smaller doors (unless I'm parked closely to someone). I do love the rear wing on the sedan over teh coupe though...decklids ftw.
BTW, J's makes an exhaust that fits for coupes, as well as front lip. Not too hard to see a Japanese company making stuff for USDM market as well -- we spend so much freakin' money on there to do so. Just because Mugen won't, doesn't mean that someone won't see the brilliance of catering to us JDM lovers that are here.
My favorite Subie is the old 2.5RS Coupes. Buahaha!
