Price Advice Request

[Lowe119]

I have a coworker inquiring about buying my parts from my bike and I don't know what to charge. I don't want to ask too much and I don't want to give them away either (in case someday I want to ride my bike on the road). So what do you think about the following parts:
Guages( is it even good to sell this?)
Mirrors
Lights

Thanks

I'd suggest going to ebay and searching for a similar part, then checking "completed items" to see what prior sales went for.  That way you have some basis for the price you're asking and there won't be any question in his mind.

I think a general rule is half of the retail price.  Guages might be a little higher.
