March was a huge month for auto sales, and even as 1.4 million car purchases were made, a mere 1,200 or so sales stand out. That’s how many Prius Cs were sold during the first three days they were available to buyers. The C, a slightly smaller version of the Prius, which is undoubtedly the king of all hybrids, starts at under $19,000 and gets 53 mpg in the city, 46 mpg on the highway. Although the C is brand new and somewhat unproven, it has gotten off to one of the hottest starts in history among small cars.
