In the market for a Yaris

[33OH]

^ Yep, an "S" lip kit and slightly different seats.

You mention '05 to '10, they actually weren't introduced to the U.S. market until 2007, and there is no real difference between an '07 and an '08 (besides the '07's not having TPMS sensors - which are a pain anyway.) So I would broaden your horizons to include '07's as well. The '09s got a slight body style change but nothing major, the headlights indent a little and the bumpers are a little different.
