Jamie, I did the same thing, only I spread the cost over about a ten year period.....
I only recently finished off my interior. I did my own carpeting and door panels, which look okay but not nearly as nice as the E-M carpet & upholstery kits look installed (just a lot cheaper). I never wanted it to be a show car, but even with an el-cheapo interior and an occasional wash and wax, it still never fails to take a trophy every time I do show it (local shows only).
The headrests look good, and I know you tall guys need that extra bit of support to keep the wind and high-G acceleration from slamming your heads back....
Something I don't have to worry about since I'm vertically challenged (only 5'7")
What replica wheels did you go with, they look real sharp. Are you planning to install side emblems? What induction system did you install? Do you have any engine bay pictures? Sorry for all the ???, just curious...
