Yeah the initial listing fee is only �6.00 per catagory Norman, but if you have 2X catagories, bold, highlighted, featured etc, then it can mount up to a fortune and �40 is quite feasible ( I sell a lot of px's on there).
As everyone said, you won't get charged a FVF, but you will get charged for whatever your ad costs whether it sells or not.
If you want the earth for your car then you'd be better off with auto-trader or a local paper to be honest, as ebay is like the Wild West, and if you sell again, start the price low.Good luck.
