Saw this at Old Holden Day today. HR Premier wagon with factory Opel 4 speed and a 186S. I spoke to the owner who said that it was an early Opel build but it was ordered and built with a 186 and 4 speed as a specific order even though the Opel was only available with 186S at that time. The current owner bought it off the original owner I think, and happened to have a 186S. He drove it as a 186 while he rebuilt the 186S, then put that in. He said this car has been featured in Restored Cars and one a couple of prizes at past shows.
