@oouthere, welcome here!
If I would be in your place:
Xtown three years younger and in way better optical conditions. For spareparts is always a piece to be found or to be repaired by a bodyshop. Any "plastic" body part can be welded and repainted nowadays, even if you bring it in to them in shambles. So I would not worry too much about bodyparts.
Burgman looks to me a little bit neglected, I personally would doubt this "less then 2000 miles", maybe kilocounter was changed. As for spareparts/ bodyparts same story as for KYMCO, on order or not deliverable.
In my experience KYMCO produces quality which is only failing because owners/ people abuse this scoots by NOT maintaining, NO oil change, NO cleaning after saltbathing, ect.
For the same $$ a younger scoot, I would go for the XTown.
Maybe you get a little discount to buy a rack and topcase.
BTW, in this forum you will get all support you need.
