For non trade sales (less than 6 vehicles in a year) eBay rates are very competitive, a listing fee of tens of dollars depending on options selected and $125 selling fee.
I would be tempted to set a healthy reserve and see where bidding goes intially and if it doesn't sell relist it slightly lower. Project Pantera shells with an accompanying box of bits have been selling close to 30K recently. I think there is a sub market for people who want to get in at that level.
