what's it worth?

Hi all, I stepped up to a Massey Furgueson SCUT, and am selling a 4 year old GT5000 HST, 54" deck with an extra set of blades and deck belt to a co worker. It has 105 Hrs on it was stored inside and serviced yearly (oil, plugs, all filters). I told him $1100. Is that fair? Thanks in advance.
