This is the car that started it all - the box car that launched the box car trend is the Scion xB. It was imported from Japan in 2003 as a re-badged Toyota bB, but included a few differences for the US market. The engine was bigger, a spare tire was included, and of course it was changed to left-hand drive. For its first 9 years, the Scion xB was the highest selling Scion in the US with over 285,000 units. A small percentage of those were RS models, a low-production run of vehicles packed with optional equipment and painted a unique, one-off color. Major contributors to the xB's success were its strangely appealing boxy style and low sticker price, plus the aftermarket Scion xB parts that are available for interchange and customization give buyers the feeling of driving a vehicle that's uniquely theirs. Fun fact: the Scion xB was initially marketed to buyer's in their late 20s and early 30s, however a 2009 review of the vehicle claimed the buyer's average age was 46.
