Buyers drove off with 10,225 Mustangs in May, compared with 8,931 Camaros. The shift marked the first time in months that Ford managed to overtake its biggest competitor, thanks in part to large incentives geared toward moving 2010 models out of the way. Buzz has been building about the new 2011 models for about a month now, and chances are some buyers looking for next year’s model may have found a deal on the remaining 2010s and pounced.

Of course, one month doesn’t make a trend, but it wouldn’t surprise us to see Ford keep up the momentum, especially as consumers start placing orders for the new 2011 Mustang. The new car is more efficient and more powerful, both in V6 and V8 trims, and the company has been doing its best to get the word out to every nook and cranny of the automotive universe.

At this point, the Chevrolet Camaro has been on the market for more than a year, and consumers are already beginning to grow numb to the car’s “newness.” GM isn’t blind to that fact, though, and the company has a few plans in motion to keep the car fresh in the eyes of the ambling masses. Next year we expect to see the arrival of the new Camaro Convertible for the first time in years, and the Bow Tie faithful that have been waiting for the car to show up on dealer lots will likely come out of the woodwork, checkbooks in hand.
