I think LH F is up to "Made in Germany" standards, just like 15 year old Mercedes. It's not up to the latest fashionable design (and wasn't even when it's introduced), but it does it's job perfectly, and will probably still do when it's sold to another country in 5 years. And just like that there's a lot of happy customers while other people are rather interested in the latest ever-changing fashion..
Mercedes was able to launch THREE new S-class models while Lufthansa was sticking to its F seat...
