Bike selling advice needed

My wife has an '04 Trek Navigator 200 she wants to sell. She did a few training rides and then did a century, and that was it for her. Does anyone have any idea what we should sell the bike for?
Retail was 379.00 US$

Used bikes usually go for anywhere from 50 -75% of original cost depending on condition.
At least that is my observation.
