The car I sat in was a prototype (ie. American car). I was told that the Canadian version would not have any of the red accents in the interior but everything else would be the same as the prototype.
They are still working out what will be included for the Canadian model (as well as which accessories they will be selling) which also means they don't have a final price yet as it will be based on the decisions they make with regards to what is included in the car. Heated seats are confirmed out though
Scions in Canada (not sure about US) do not have trim levels, so they have to carefully balance msrp vs. standard equipment since there is only one model.
