Ferrari Enzo – $2.6 million
The most expensive car ever sold in an online auction at the time of its selling, the Ferrari Enzo was produced between the years of 2002 and 2004. There were originally only 399 ever made, in classic Ferrari tradition. However, a 400th was, indeed, made as a gift to Pope John Paul II. This wasn’t the one that sold for $2.6 million, but still auctioned for $6 million itself. This particular Enzo was one of the highest fetching cars of its line due to the fact that it had fewer than 1,250 miles on the clock at the time of selling.
