I disagree. Although I've not sold a car of my own on eBay, I've put together HTML listings for two mates who have. Went to town on both listings, with loads of detail and pictures, and both cars sold really easily with loads of enquiries and they made more money than was expected.
Just put lots of warnings to ward off timewasters, insist on bank transfer only, start at the minimum price you'll accept (don't put on a reserve) and away you go.
