is the toyota scion the same as a toyota sequoia
Same as in what? The Sequoia is Toyota's full size SUV. Scion was a marquee and or Toyota's brand to market to vehicles to younger people. Toyota started selling them in 2003 and it was absorbed back into Toyota in 2016 and no longer. There we're a few different vehicles associated with the brand such as the Scion XA. XB, TC. etc.
Exactly the same. With the two side by side you can't tell them apart.
