I'm disappointed with the lack of a daytime-visible display on the stereo, and not especially impressed with the sound, particularly the rather muddy bass. So I'm likely to follow X-fired's lead and swap out the audio system first. X-fired, does the McIntosh head unit you used blend in with the console treatment, or does it stand out like a sore thumb the way that black Alpine navigation unit does in the pics that someone put up in their gallery? (No offense intended to the Alpine poster, by the way. The sore thumb thing is purely a subjective judgement of personal preference.) Also, what sort of sound damping material did you add? Are you talking surface materials in the cockpit, or stuff inside the doors, the wall behind the seats, etc.? I hadn't really thought about it before, but depending on the design, those cavities could be part of the cause of the muddy bass.
Aside from the stereo, I have to admit that I find those cheesy illuminated sill plates attractive for some reason. And I have to agree with kusheen on a couple of points. I'd love to see a reasonably-priced way to increase the power, but the lack of such seems to be mostly par for the course with normally aspirated cars these days. I'd also love to see a replacement for the silver plastic in the center console, though I'll leave the carbon fiber and wood treatments to kusheen. I'd prefer a brushed or anodized aluminum finish, myself.
Cheers,
Greg
