Gumtree is a WHOLLY owned subsidiary of eBay. Disappointing most people think it's a privately owned, Australian business.
As far as freemium sites go (sites that make you think they're free but really do the hard-sell on "upgrades"), they're well ahead of most of the competition. If you're selling or buying a VERY cheap car, they're probably the best of the free-to-list sites.
