Steve,
The 1600Ti with the extra mirror is my car. It's an old picture the original owner had from when he used to road trip with his family from Alberta, Canada to Disneyland. The car still has the extra mirror-- and the stub of the original mirror. Interesting choice that has lasted 30 years or so at least.
Despite the different colors, I'm 90% sure this car has its original nose panel and fenders (what's left of them). That reddish color I think is some experiment at priming or remediating rust at some point. But the nose panel has no snorkel. Also the front trim piece on the car is dimpled.
Maybe there were very early 1600Ti's without blacked out grills, and then BMW started blacking them out on the 1600Ti when the 2002 came out? Unknown to me, but I've never seen one, or a picture.
I have the same 3 page 1600Ti brochure, dated July, '68, but printed in German.
