I dont know man that sounds pretty low. Try craigslist for around 500-700. You never know what they might give you. Or you can just try to sell it to a junker for scrap.
There is a guy in College Station and another in Caldwell buying junk cars. I know there are quite a few others around but I dont have any of their contact info.
I always hear the guys on the radio talk about the Houston Can Academy. They come pick up your car and take it as a charitable donation which allows you to claim up to 5K? on your taxes. Not sure on the dollar amount but might be worth checking out.
