A quick Google search brought me the information. It appears you may choose from the entire Toyota/Scion lineup, including hybrids which may help those who are on the fence about purchasing one, or would like maximum MPGs when taking their upcoming summer road trips. It is not immediately clear from the website if there are different trims available for the different models, or what models are actually even at your local dealership. You are directed to a form to contact them for more information, instead.
