I had to have the evaporator in my car replaced last week and the mechanics told me that while they were there they'd replace the heater core too. I didn't know whether that was necessary or not but I'm assuming it was in the same place (in the dash) as the evaporator and they figured they'd replace it while they were there.

That being said, I now have a perfectly good heater core that they removed from my car and I'm wondering if this is something I could sell or if I should trash it? I don't know if this is the kind of part people are looking for used.

Thanks.
