I put 11K miles on my 74 Tii last year alone and can attest that, even without all the modern conveniences, these can be reliable daily drivers. Good call on bringing back the factory color, from the looks of the engine compartment that is Inka for sure as Colorado is much lighter.
Albeit a roundie but this will give you some inspiration and an auction to watch:
