Honestly, the ad page itself screams scam.

"USED [...]/FLIPPERS" - who calls the machine flippers? But I could let that slide as someone just being strange. But once you start reading the descriptions:

"only if connect the display its are in short circuit"
"good general shape , but not start blows the fuse of alimentator box , **any stupidity**"
"just little usually wear on 'terrifyng ' write"

All of these broken sentences, including many that are just gibberish. It reads a lot like the common "hello I am a rich prince" scam.

I'm glad OP didn't get screwed but there are a lot of red flags that should warn people to not even make the first contact.

But the ad wasn't in Europe. That's my point. Like I said, the descriptions read exactly like the poor wording and spelling you'd find in the old (though still extremely common) rich prince scam. The people originating those scams are, statistically speaking, almost never primarily English speakers: https://www.bbb.org/new-york-city/get-consumer-help/articles/the-nigerian-prince-old-scam-new-twist/
