You might look at the Ford Tbird(the new ones) Inspiration Yellow. It's not pale or brassy but just right.
Looks great! Frenched headlights will finish it off nicely. I think black/dark blue plus a white top will look eleganza!
Wow, I missed this thread until I went looking to see you've posted any updates lately, Jim. The Merc is looking absolutely awesome, and you must be psyched to see it outside and at a shoe to boot!! Adam's quite a craftsman!...whats next in the work plans? I have to agree with the other guys about going with a dark color, yellow isn't going to work, besides there's already another yellow Merc ragtop running around!
