The '69 I owned was Cortez Silver with a black vinyl top and black interior. It was actually pretty sharp-looking. It had the factory black grille option too, which I think made it look better with the silver paint. It was a basic 350/350 auto car, with buckets & console. No AC. Had original CA black plates too, which is actually pretty hard to come by on Camaros & Mustangs in particular, in view of how many times most of those cars changed hands since the '60s!
My '13 has much more power and turns and stops much better too, though!
I think if money were no object, I'd buy a professionally restored black '67-'68 SS 396 L78 (or maybe with a 427), with an M22 4-speed. Maybe with a red interior, but white would be cooler for SoCal heat.
Second choice would be a '70 'Cuda with 440-6 pack and 4-speed, maybe also black, but I like the In Violet color too (which was the Plymouth version of Plum Crazy on Dodge models).
Third, I would go for a '13 ZL1 with 6 speed in Black.
So, all things considered, I think my '13 1LE isn't far behind in this list.
