Panerai purchase questions

[sunset117]

Hello,
I’m considering buying a panerai
Specifically; Panerai Luminor Marina OP6518 Manual wind Men’s Wrist Watch 44mm

I was able to haggle down to $2800 cash meet in person. I’m wondering if that is a good deal? The watch has some wear, and multiple scratches on the watch case back and could use cleaning but has zero mechanical issues and has no winding problems.

No boxes or papers

I’m hoping this will be my new daily watch. I love panerai but can’t afford new. And the scratches bother me but atleast it’s the back.
