Why would someone want to use your site over the better established sites that do the same thing (Craigslist in the US, Gumtree in the UK)?

good question. We are trying to be more of a social classifieds site where for example users can chat online with the seller or private message them. Sellers can also upload a profile so buyers may feel more comfortable with them.

Also, we are aggregating other sites such as cars.com on the us site and other local classifieds data, so it's easier to find stuff in one place.

But definitely that where the challenge lies.
