Pricing Advice Needed

[at t 2d]

I have an AlkyControl methanol kit for my TTA that I started installing about 2 years ago. I got as far as the pump, reservoir, and radiator overflow and never got back to finish the install. I've decided just to sell it at this point since I rarely drive the car any more. I don't have the plastic housing for the controls since I was going to mount them directly in the dash, but I do have a polished and drilled up pipe. Any ideas on how much I should list it for on the auction site would be appreciated.
