I got the following from eBay for about AUD $15 which was pleasing. They're a mixture of Lledo (x1) and Corgi (x4). The Lledo vehicles are a fair bit nicer, especially the wheels. The Corgi wheels have a very cheap look and feel about them.

I've got another nine vehicles of different sorts on the way, also from eBay. That should do me for a while I think given I still have to clean them and and repaint where necessary.
