Selling a car, Carsoup? Ebay?

[TurboDomestics]

What do you guys think of selling a car on carsoup or ebay? Is it worth it?

Im talking about the Spyder GSX that's in the classifieds. I have it posted on the free sites so far. But I'm trying to decide if it is worth posting on the pay sites like carsoup or ebay.

I tried to sell a GVR4 a few years back on ebay and was very disappointed in with it.

What do you guys think? Its obviously not something that your everyday person would want, so I'm not sure if its worth the money to market it on the pay sites.
