My friend bought a brand spankin' new Yaris a few weeks ago and she loves it (she's coming from a Celica ZR lol). So they are excellent little cars. In terms of knocking prices off, I'd go as low as 2k off. Do what dwee. and the others said - look for any faults such as scratches, etc. to bring down the price. I bought a Corolla Levin for my mum last year and knocked off $3600 from the advertised price. Don't be afraid to haggle and don't get too excited when you inspect the car lol. Good luck!! :D
