Nice list!
As a suggestion, the chrome rear spoiler may look better in black carbon fiber because of the already chrome Chrysler wing emblem on the rear end. I think it would be sharp with the black cloth top.
The Valentine 1 has a large head unit and may block a good portion of the windshield. My detector is mounted in the center of the rear shelf and I use the audio alerts. I have a Coupe and it detects front and rear signals perfectly in this location. The Roadster rear shelf is a couple inches higher than the Coupe.
I'm also ordering the clear side markers from CTD Germany. A very nice choice. I've always liked the cleaner Euro look of these lenses.
Good luck! We'll be looking for those photos.
