I finally decided on painting my Chevelle "Le Mans Sunset", which was a color option on the 2003- series of Nissan 350Zs. It's a great copper-bronze type color that's very metallic and I thought it would look awesome on my classic muscle car.
It's also nice to have a real production paint color because you can then buy extra paint pens and even spray paint cans made in your exact color, great for any future touch-ups or extra projects like painting your brake calipers to match, etc., which is something I did plan on doing eventually.
