seperate 'wanted section', in classified

[eddie man]

Question: Why is it when I look on the classified, for example 'Lotus Elise page', I see adverts for wanted, companies traders etc, wanting to sell your Lotus? If wanting, then these should be in a 'wanted' section, surely. People who are looking to buy have to go through all these adds, to then determine they aren't relevent to their search. Bit annoying, that's all.
