Penrith and Castle Hill Toyota parts are great for import parts and have a formal close relationship - may even be sister companies or the like. I deal with Mark at Penrith Toyota regularly and enjoy the benefits of excellent service and substantial discounts via Australia Lexus Soarer Owners Club membership. They have the Toyota JDM parts catalogue and can get parts/prices quickly as a result. They are also official TRD and TOMs distributors if you are that way inclined.
