Wonder no more. Toyota has officially launched the online configurator for the 2010 Prius, which allows you to create your own hybrid with exactly the options you want and find out just how much it's going to cost. For what it's worth, we created our own Blue Ribbon Matallic 2010 Prius III with the Solar Roof and Navigation option package and Remote Engine Start, which allows the driver to cool the cabin down using the air conditioning before entering. Total cost after delivery: $27,879. Thanks for the tip, Bill!
