What would be more Expensive...???

Hi there, i have a 2000 civic sedan and just got my stock motor completely rebuilt. As of right now, it has like under 50 miles on it.
Would i have gotten more money with my original nonrebuilt motor with 28k and no warranty, or the rebuilt motor with 50 miles and a 50k mile warranty?
It just seems like people would be skeptical when they hear that the engine was "rebuilt"..

thanx in advance

Why was the engine rebuilt with only 28K? Honda engines should last a good couple 100K's. When I worked at Honda it wasn't uncommon to see cars with 400K on the orginal engine.

maybe this will clear some things up.....
