Are there any figures relating to how many total 67 L78 (4K) Camaros were built at Van Nuys, and what the breakdown between MR and MQ coded cars was?
Not that I know of.
From DMV records, it appears that my car was first sold to a consumer through a Chevrolet dealer in Reno, NV, which makes me wonder why it was K19 equipped given that it wasn't sold in California. I suppose it is possible that it may have been originally produced to be sold at a dealer in CA, but dealer transferred to Reno?
That's probably it exactly. While I don't think it wasn't typical, it probably wasn't unheard of for dealers to transfer cars, so you probably got one originally destined for sale in California.
John, can you comment on transferring cars from one dealership to another? I know it's common nowdays, but what about back then?
