On Thursday, official announcements by General Motors Co. confirmed that US sales of the automobiles manufacturer for the month of March managed to rise by as much as 43% at its four surviving vehicle brands, with a major lift being provided by crossover vehicles and cars.

GM revealed that sales of Chevrolet, Cadillac and GMC brands hiked by 41%, 42% and 45%, respectively. In addition, there was a whopping 76% increase recorded in the sales of Buick. Overall, total combined sales for the company's four brands were 185,406 for March.

Total sales recorded by GM, which include four brands that the auto maker is now stopping, recorded a 21% rise. March of 2010 had 26 selling days, which is one more than the previous year, which also helped.

The positive results have come after GM revamped its North American sales operations last months, for the second time in four months.

Competitors Hyundai Motor Co. and Toyota Motor Corp. have also been posting positive figures, indicating a definite improvement in the automobiles market.
