The fees for selling on eBay Motors can be found here:
Motors fees.
At a bare minimum, you're looking at $90 to successfully sell a car there - $40 insertion fee, then a $50 transaction services fee if it sells.
When I list something on eBay, I prefer to supply my item description in HTML (composed using free software), and include relatively small pictures that are "clickable links" to much larger, nicer pictures - all of them hosted somewhere other than eBay. If that seems like too much work, of course, you don't have to do it that way - eBay will be happy to host your pictures for a price.
I guess my first question would be this: why use eBay to try to sell this particular vehicle? I think of eBay as a way to get nationwide (or worldwide) exposure for something really special. If I had a relatively common car with some issues, I'd be thinking of Craigslist first, with the expectation of a sale to someone relatively local to me.
My two cents.
