Is the quality of our cars getting worse and worse?

Hello everyone, i.e. with the afforestation of professional forums, from the acquaintances and also from own experiences, I notice an increasing decline in the average quality of our cars. If one could find in the past a more or less constantly increasing product quality everywhere, so up to about 2010, so since then constantly the quality, which all manufacturers are affected by. Who now buys a new car, gets again rust immediately supplied (if you look at the underbody on new cars that have not yet been delivered, while you look at thick layers of underbody protection in the past or on cladding parts, you see now naked metal, which has of course already set rust), the equipment is continuously slashed and simplified, so you pay partly still approx. 1000 Euro extra for BiXenonLight, but get instead a saving version with reduced light yield, but without automatic light ranges control and without cleaning system, not even emergency bikes are supplied as standard, even for this you have to pay 100 euros! A “real”, usable spare wheel has not been available for a long time, instead such tire glue with compressor, which however irrevocably destroy the tires when used. And some cars don’t even have that anymore, but instead they have RunFlat-Tires, i.e. tires, which you can also ride flat. nz considerably, but what’s the point, the manufacturer saves and the crazy customer buys the car like that. Do you also have this impression, or am I wrong? Greetings Udo
