Troy, As you can see in the magazine
article it was painted white with owner's names/logo, which like Joel says was pretty ugly? But it wasn't painted by Motion from what I have. The set of 3 Motion Invoices total up to one combined total on the third page with no inclusion or price for any paint work. I assume an outside shop must have done full re-paints for Motion, or the customer shopped it out himself. That must explain why you saw a separate invoice.
When owners make color changes like the White, then Blue, and then this Black with red stripes, I don't consider that as any Historical value to what Motion did. It would be like an owner changing a 69 Yenko Camaro's color to Red and you wouldn't restore it as a Red Yenko as it has no Yenko historical value (plus Incorrect).
