So I have 2 Traxxas 1/10th scale Rallys...

I don't really use them ever since I got backed out of my job ever so gracefully ( :P )
I am really wondering what I should ask for them, I have Big Bores on one, I have a set of the blue aluminum Traxxas shock towers waiting to go on one. They have both been run for about a month before being thrown in the closet. :-/

Any assistance here guys? What should I ask for them? Should I even sell them?

Edit: I actually have a few other extras, another stock body, a painted JConcepts Scalpel body, a Toyota Slash body (long story)

If they're in good condition (minimal signs of wear, no parts needing replacement) and come RTR with a few spare parts and odds and ends (batteries, bodies, tools, tires, etc), reasonable starting asking price is about 75% retail.

IMO the extra parts like the shock towers and bodies ect don't really raise the price. They are just for an added incentive for someone to want to buy the cars more. Generally used rc stuff goes for around 50%. The reason people buy used is to get a really good deal, otherwise most people would rather buy new and have the added assurance. What I usually do it add up what my stuff costs and half it. Like Reme said, about 75% is a good starting point, and is usually the best you can hope for. But as time goes on in my experience, you'll keep dropping and dropping the price and usually around 50-60% of retail is when you'll start getting bites.
