Having posted a 12 percent gain for the month of February, General Motors is on a roll.

The General’s total sales for the second month of 2010 came in at 138,849 units. Out of that number, 6,482 units came from the Chevy Camaro, which passed the 75,000 units sold mark, beating the Ford Mustang every month since its reintroduction. Overall, however, American rival Ford tallied an inch higher than The General, nabbing a mere 334 more sales to hold the number one spot in the U.S. for February, with GM being number two. That is unless you’re still counting Hummer, Saturn, Pontiac and Saab, which boosts GM’s bottom line to 141,951 vehicles.

GM’s four core brands – made up of Chevy, Cadillac, Buick and Grabowski Motor Company (there’s a trivia fact for you) – grew a spurting 32 percent compared to last February, with each brand having at least one standout model. Here are a few year-over-year (YOY) highlights compared to outgoing nameplates:

• Chevy Equinox grew 132.8 percent
• Buick LaCrosse is up 163 percent
• Cadillac SRX gained (a staggering) 541.7 percent
• GMC Terrain up 303 percent

This is the seventh month in a row that these four have posted triple digit YOY gains.

From a brand perspective:

• Chevy soared 32.35 percent and moved 99,999 units
• Buick blew up 47.21 percent – more than any other brand and and recorded 9,121 unites
• GMC came in at 20,496 and expanded 26.24 percent
• Cadillac climbed 31.76 percent, recording 9,273 units

This is great news – and with the recent executive shuffle – let’s see how The General’s new marketing and sales structure will affect March and April!
