Everybody has to make their own decisions, and some are limited by funds (not assuming anything here nor attempting to degrade anyone), but I prefer to not inherit someone else's problems. I buy new 98% of the time, no matter what it is. I almost bought a used 2020 P1K5 in Camo with 900 miles on it. I held off, eventually scoring a brand new one for literally $99 more than what they used one would have cost me (after dickering with the seller). Many say the factory warranty isn't worth much, but I beg to differ.
When it comes to "Well, it has this accessory and that farkle on it", so I'm saving $ on not having to buy and install that: Sorry, but I prefer to purchase and install my own accessories. That way, I know it was installed correctly and I get to decide what is and isn't installed on *my* bike. Blame that on my mild OCD and/or I just want "my stuff" to be "MY stuff". If holes need to be drilled or something needs to be cut or modified, (a) I want to do it and (b) I want to know about it. I'd hate to "find" something down the road that I didn't see before buying it.
Look at it this way: If the used one was sitting side by side next to a brand new one, which would you buy? Point being, don't let TIME be a primary determining factor in your decision. You've lived this long without it, what's another month or even a few more months?
If the seller stopped communicating once you started asking questions, I would consider that a blessing. S/He might realize they aren't dealing with some idiot who's going to pay top dollar to buy a used machine (potentially) with someone else's problems.
