How to tell if dell is new or refurbished?

Question

Dell

I want to buy xps for myself, I looked closely at prices, somewhere cheaper, for example, in the same player ru, but something is suspiciously cheaper. Somewhere more expensive.
I read the articles, I also came across that on the off site of cases you can check the guarantee, but what exactly should be there, which would confirm the "news" for the laptop, is not clear.
It is advised to take a manufacturer's warranty, but what does the manufacturer's warranty look like?
Do they give it at all?
I heard that there are companies that do not give their guarantee at all in Russia because of some of their policies. Subject
