The Ford Mustang outsold the whole Lincoln brand by a 1.5-to-1 count in March. U.S. Mustang volume has, not surprisingly, risen sharply since the age of the sixth-generation model began.

March’s tally, however, was particularly notable, not just because of the way in which Mustang volume made Lincoln’s abysmal total appear even worse (Lincoln sales slid 3%, year-over-year, to just 8695 units) but because the Mustang outsold the Chevrolet Camaro and Dodge Challenger, combined.

That won’t become a long-term trend. General Motors is already gradually leaking details of its next Camaro. The Challenger, meanwhile, is selling better than ever. Sales have only increased on an annual basis since Dodge brought the nameplate back in 2008.

Nevertheless, the Mustang’s March total of 12,663 U.S. sales was, according to Ford, the “best performance in eight years.”

More precisely, Mustang volume hasn’t been this healthy on a monthly basis since June 2007.

Remember the summer of oh-seven? Yeah, Bush was president, Craig Biggio was still playing baseball, and you were singing all the words to Umbrella in a rented Caliber. More importantly, the Camaro hadn’t returned from its lengthy hiatus, and the Challenger was still months away from being available for order.

In that era, 12,781 Mustang sales wasn’t all that impressive. Ford averaged nearly 14,000 monthly Mustang sales in the United States the year before.

But in 2015, when the overall passenger car market isn’t quite as large and in decline, when competitors of various types are attempting to steal sales, when most other Ford cars posting decreased volume, the Mustang’s surge to 12,663 March sales is rather impressive.

The Mustang was America’s 18th-best-selling car in March 2015 and finished the month just 68 sales back of the 17th-ranked Kia Soul. Besting vehicles like the Subaru Outback and Volkswagen Jetta, the Mustang accounted for 17% of Ford brand car sales, significantly more than the Taurus, Taurus Police Interceptor, Fiesta, and C-Max combined.
