Change it! My 71 GTX, ALL #'s matching was originally gold with amber gold interior. I changed it to Sassy Grass green with white interior and sold it right away just a few weeks ago.

People look past green cars (except high impact)
all the time. But, it was R4 or R6 red or B5, they stop and look. Same way if you expect to sell it to someone for an investment.

I had a 70-340 Dart that was F8 and I painted it F1. I was glad I did, I loved the yellow paint. It really stood out.

I like F5 and F8 green, its just not a good seller or investment grade color.

Have a tag made for the gawkers and keep the original.
