I wish I could say just "no" but nowadays you can't be sure where used laptops have been anyway. If you can't buy a new laptop, you could as well just buy one that has been in China.
Thanks for your reply. Somewhat a different topic, but do you think it would be ok for me to ask him? He has a Chinese family Name and has heritage there.
I did buy the laptop and I did ask him. And I feel kind of bad about it. I tried to communicate as good as I could in the situation about why I‘m asking but we had a bit of a language barrier. I think he got where I‘m coming from, but didn‘t really understand my worries.
He claimed that the laptop was bought ‚here‘ and never went to China. He then showed me a bunch of other things that were bought there and how this is not a problem. Well…
Nevertheless, I wanted a Thinkpad for a long time and think I got a good deal. For those interested: T470S (2017) i7 16RAM 500SSD 350€
