Not that I'd have ordered it this way from the factory (black with olive interior), but it's proof positive that you could combine any exterior color with any interior trim color you wanted back in the day. Really nice truck (ebay), jury still out on the interior color for me - but it is very nice, and I think it's a very interesting piece of chevy truck history! Ok, the color combo IS growing on me I think!

Just noticed a black with blue interior one the other day also (still on ebay I think), however owner re-did the black ext in metalflake black.
