Yes, Ernst Leitz GMBH is no longer only a place for mechanical and optical perfectionism. Leica earns its living from fashionistas, and does spend cash on ads and image-building in order to keep volumes up, not just on technical excellence.
That should not yet scare away quality-conscious customers. Repair prices cover costs. Not just costs for what faults one may have noticed, but also costs for making the equipment conform to its performance as designed, cost of taking on trainees and costs of keeping spare parts (although that seems to be going).
I have had three encounters with Leitz\Leica repairs. Once, a long time ago, at wetzlar with a IIIc, once with an M3 at the local importers and more recently with solms and an R 35-70-ROM. Leitz\Leica went through all functions, not just the ones requested.
Their reasoning as explained a long time ago by a works representative at the Hauser Torwerk in VVetzlar was that once it left the service there should be no reason to complain about functions, so they did not reinsert, but replaced all screws that had been undone, tested and, if needed, adjusted all functions. Customers implicitly agreed with this. Rather like needing to put in a car for service to fix one fault, but also wishing to have it serviced to perform as new when you got it back.
I presume that one may ask that existing, but unnoticed faults should be allowed to persist, and that the repair then would be cheaper. No idea whether the company still tries to serve serious users, but I do hope it does.
