The restored Sidchrome Imp carries the correct signage, or it did the last time I saw it. Sometimes if you ask the wrong person (ie anyone but the owner of the Sidchrome Corporation) you just get 'No' for an answer as it's the 'safe' answer to give if they're unsure. I wonder if George had just gone ahead and painted Sidchrome on the Mustang, whether anyone at Sidchrome NZ would have known or cared.
