"So far so good!"
Translation:Så langt så godt!
It's actually something we say.
I have to disagree. I clicked on the comments exactly because 'så langt så godt' is not something that Norwegians say - I've never heard an expression like that. The only way it could enter the language is as a bad attempt to use an English expression. And there are unfortunately a few of those that, for some reason, some think are ok to 'translate'. Another pet peeve of mine (something I've actually seen, unlike the sentence in question) is 'fortell meg om det', a literal translation of "tell me about it", which absolutely does not work in Norwegian.
Well I am not Norwegian so I don't know. But in German we use the same thing: So weit (weit = far), so gut. It therefor is not only English which uses this expression. So I don't see why it would sound so weird in Norwegian, since a lot of times it seems Norwegian is right in the middle of English and German.
The problems with the (non-existing) answer sentence are severel, not the least that "godt" doesn't match the meaning of "good" here. The sentence really sounds clumsy.
