I'm not sure that being candid puts off bidders on ebay, sometimes it's the opposite. A friend listed his old Toyota hilux (pretty much a total wreck) on there a while back, he was brutally honest about how knackered it was, long, long list of what was broken and rusted. When I read the listing I thought it was a waste of his time and nobody would be interested. I couldn't believe the bidding, loads of interest and it went for a very good price. Sometimes brutal honesty seems to be a good selling tool, lol.
