Ford and GM have recently engaged in a war of words over the sales figures of two of their models, the Mustang and Chevy Camaro.

The current iterations of these classic cars are close competitors, and sales between the two have been close. The companies proved they weren’t above a little mudslinging in marketing these new vehicles.

Press were invited to test drive the new 2011 Mustang, but not before Ford brought out a brand-new Camaro in order to point out all the ways the Mustang improved over Camaro’s design. When the May sales figures were released, Ford appeared to have gained the upper hand by outselling Chevy 10,225 to 8,931.

Some analysts were quick to point out, however, that Ford was offering steep discounts on 2010 Mustangs in order to make way for the new models. And Chevy released a press release detailing that it had outsold the Mustang by nearly 7,777 units over the first five months.

Those who like a little muscle in their car would do well to check out the used car market. As the two giant automakers trade blows, savvy consumers can find great deals on used Ford Mustangs and Camaros.
