Hi, what a great thread

For the record, the Austin & Morris franchises were divided equally and that there already had been quite a clearout of dealers/agents by this point.
In terms of the garages mentioned so far:
McCairns were always Vauxhall, but I think they also had the Chevrolet and Pontiac franchises. They were also Alfa Romeo distributors before Caveys (and I think there was a gap too). McCairns had branches in Galway and Waterford as well and before they ceased trading they had become Opel dealers due to the phasing out of Vauxhall in the early 1980's (1982, I think).
Joe Keane had branches in Taney (Goatstown), Sandyford, Stillorgan (Topaz filling station, now), Rialto (Rialto Motors, now), Clondalkin and Lombard Street. I think they went out of business on the same day as Smithfield (I was about 10 at the time).
In terms of PMPA, a lot of these were originally owned by Brittain's and were named Portobello Motors.
I have a few bits and pieces especially about the BL makes if you're interested.
