When the Scions first came out a magazine I subscribed to wrote a review of them. A couple of months later they printed a letter from a reader who said something like..."If they couldn't think of anything better to name them than 'XA' and 'XB', why didn't they just call them Sludge-Pump A and Sludge-Pump B."
I tend to agree, but they are made by Toyota & I can see where the boxy one might be handy if you were in a band or something. And just about anything looks better than a Pontiac Aztec.
