SANTA MONICA, Calif. — This month's new-vehicle sales (including fleet sales) are expected to be 1,119,700 units, a 30.9 percent increase from March 2009 and a 43.9 percent increase from February 2010, according to Edmunds.com.

Edmunds.com analysts predict that March's seasonally adjusted annualized rate (SAAR) will be 12.4 million, up from 10.3 million in February 2010.

“Although this SAAR sounds promising, it’s too early to wave the flag and say that the economy has turned the corner,” Edmunds.com CEO Jeremy Anwyl told AutoObserver.com. “Incentives drove sales this month, but those were defensive moves in response to Toyota stepping up incentives and are unlikely to last because inventories are simply not high enough to justify them in the long term.”

March 2010 had 26 selling days, one more than last March 2009. When adjusted for this difference, sales increased 25.9 percent from March 2009. (The chart below sets forth other unadjusted and adjusted comparisons.)

"What a difference a month makes for Toyota, whose sales climbed 80 percent since February thanks to generous incentives and more balanced headlines," observed Jessica Caldwell, director of industry analysis for Edmunds.com. "At this point, Toyota seems to be making large strides in reinstating its good name and appealing to car-shoppers."
