Yes, yes and yes.
John R Weir were on King St, i’m not sure when the site was sold but it’s now student flats.
Mercedes of Aberdeen is owned by Arnie Shark (his name’s not on the building though) and are on a much bigger site with BMW, JLR, VW, Etc within spitting distance.
Not sure when they moved either, but the 2 business cards would be for the same dealer but different address going by the age of this car, because once upon a time Merc dealerships all had normal names of the owners/other company names etc. until Mercedes decided all their dealerships were to be called Mercedes-Benz of Glasgow, Mercedes-Benz of Aberdeen, Mercedes-Benz of Edinburgh etc. but John R Weir must have been one of the last to change because in Glasgow, Giffnock, Ayr and Hamilton Merc the names all changed to the Mercedes-Benz of names around 2003, JRW was taken over by "The Shark" in late 2012 I think.
Round here although the dealerships themselves never wore the company names, the cars for a while had Vardy Continental or Stratstone.com number plates and the window sticker said "Stratstone, Mercedes-Benz of Giffnock" etc.
Under Arnie the Merc garages now sell alongside the Mercedes-Benz Of stickered and plated Merc franchise stock, a range of non-franchise stuff on the forecourt with AC banners and the cars come AC plated and stickered, and if the other garages are anything like the Inverness Merc, Arnold Clark branding appears on the totem sign outside the dealership which says something like "Mercedes-Benz Smart Sales Service Parts & Accessories M.O.T Arnold Clark"
Their Merc ads were proper Mercedes corporate identity but did say "Part of the Arnold Clark Group" but saw an advert in yesterdays Road Record which was just like a standard AC newspaper ad like they do for the Ford/Renault/Vauxhall etc dealerships but for the Merc ones. They also give websites like www.mercedes-benzofgrangemouth.co.uk but also www.arnoldclark.com/mercedes-benz on the same page.
I think JRW Select which was their used prestige dealership as well as their Kia and Jeep dealerships all in Perth have completely rebranded lock stock and barrel to AC though.
