Price paid was $110 Million all cash - http://techcrunch.com/2010/06/30/woot-amazon/
According to http://wiki.answers.com/Q/How_much_volume_is_1_million_dolla..., 110 million in twenties is about 220 cubic feet.
According to http://www.usatoday.com/money/autos/reviews/healey/2010-03-1..., a 2011 Hyundai Sonata has about 120 cubic feet of passenger and cargo space.
So, assuming TechCrunch is right, the Woot CEO is wrong. It's actually close to TWO Hyundais (Hyundai?) full of twenties.
(OK, maybe one after-tax Hyundai)
