Im guessing you would like a classic looking colour and finish
If you are planning to do yourself you could use coach enamel it self levels and is nice to work with.

I painted my Roadster Connaught green the D type racing green.
I just sanded the body to remove the shiny finish, I used craftmaster primer and then enamel with the largest brush I could.
