This has annoyed me for ages!
However, over the years of selling all my car stuff I've noticed that putting less information in an ad generates more interest from buyers, and I don't just mean people asking for information that isn't in the ad but people wanting to buy the shit with no information at all. I guess people just CBF reading/lose interest after knowing all the details/are idiots/think the items might be better than they are because there is no information to go off.
