Doesn't surprise me. I had a chat with the nice service rep from the JLR garage that services my wife's XE. For all major brands, VW, BMW, Peugeot, you name it, there will always be someone to be hired who knows those cars, maybe even the older ones. For neiche brands, Volvo, Jaguar, Saab (they were the first to run into those problems around here), well, not so much. Especially for older models, new hires are trained on the more recent models on the job. So if some older model shows up at a garage with an odd issue, those folks in the free garages having only worked on a given brand for decades, have a clear advantage.
