Some advice, opinions, & taste wanted

Black with the red stripe/accents. That's what my '76 was. Sharp car. One of the ones I wish I'd kept. E58 (or E5-whatever, 360-4v)/sunroof/buckets car. Oh well. I think '76 grille looks better, not sure about flat or gloss, but I think I'd lean toward flat with glossy/factory body paint.

Mine had just the trunk spoiler and the side window louvers, I think that's all they need.

Looking forward to seeing this build, wherever you post it.
