German P226 S value

[Fishredsw30]

I’m considering buying a P226 in stainless steel made in Germany in March 2014. Never been fired and I would be the second owner. They are asking $2200 for it and I’m having a very hard time finding any information on this gun. It does have all the German marks on it and everything that came with it new is included. Does anybody have any insight on the value of this gun?
Thank you in advance!
