VW in Blacktown

Until last year, Campbelltown has only ever had one Volkswagen dealer - Sarkis Brothers, on Campelltown Rd. They began in 1963 and lasted until 1970, when they became a Toyota dealer. I dunno what happened to them after that.

Paul Wakeling, the local Holden dealer, took on Volkswagen last year, so now Campbelltown has a VW dealer again.

But Sarkis Bros - I never went there. Since there's no street number, does anyone know exactly WHERE on Campbelltown Rd they used to be? Remember that Campbelltown would have been like a little country town in the 1960s...

Campbelltown also had this private workshop, called Allwin Motors. Obviously named after their two owners, Allan Green and Winston Freer. As you can see, this ad was from 1970.

Does anyone know this workshop, and what happened to it? Anyone know those guys?
