Volvo is the best, besides that they are the only ones who got the lockdown right, so now I trust them even more.
Sadly thats not the case anymore, since Ford and then Geely took over.
<-- owns a Volvo 940 with half a million kilometers which runs perfectly fine after 22 years
Also the made in germany thing is sadly (in many, but not all, cases) a thing of the past. many companies who say "made in germany" just don't care about quality anymore. there are a few exceptions though. also I noticed a recent increase in a logo which says "Engineered in Germany". Seems like they noticed that people know that "made in germany" doesn't mean that its actually built here anymore, so more honest companies at least don't claim that any longer.
One example where I personally noticed that recently is Stahlwerk, a companie who builds welders. On my new welder it says Engineered in Germany, but its manufactured in china. the support though is here and when talking to them you instantly noticed that the people knew what they were talking about. So this is kind of a good thing I guess?
Regarding the split in east and west: as many other already said, you can't completely say "everything after XYZ doesn't have made in W.Germany on it". I remember a Grundig (?) television I serviced once, it was from the late 1990s and it still said made in W.Germany.
Also I noticed one strange thing: This prejudice that east german products are crap doesn't always seem to be true. I have acquired many eastern products over the years and even though they are most of the time more simplistic, they seem sturdier than some western counterparts of the same era - and there are still plenty of them around, as many things were made to fit multiple use cases. Like my air compressor. it uses the general purpose compressor HS1-40/70 from VEB Harzer Kompressorenwerke which was used for a wide range of trucks like tie IFA W50, S4000, Robur, several ZT300 series tractors, and in many commercial and homemade shop compressors. That thing still works great.
