Toyota's Camry sedan continues to be the best selling passenger car in the country -- with sales increasing by 5.9 percent during March of 2007. During that time, 42,254 Camrys (including hybrid versions) left dealerships -- compared with 38,981 during the same period last year.

Two more Japanese-brand cars -- the Honda Accord and the Toyota Corolla -- bring up the number two and three slots. Accord sales upticked by 5.1 percent during March of 2007; Corolla sales also held strong at 4.8 percent above the same period last year.

The fourth best-selling car in March was the Honda Civic, which posted an increase of 4.1 percent -- or 29,721 sold vs. 28,969 during the same period last year.

Chevy's Impala sedan saw sales rise 4 percent during March -- helping it come in fifth overall, with 28,505 sold vs. 24,071 during March of '06.

Other Top 20 contenders:

* Nissan's Altima sedan (number six on the list) sold 27,521 during March of '07 -- up from 23,790 in March of '06.

* The Toyota Prius hybrid more than doubled its sales, March '07 vs. March '06 -- to 19,156 sold vs. 7,922 sold previously.

* Chevy's Cobalt and the Ford Focus compacts are in a virtual dead heat, with sales rising 2.7 and 2.5 percent respectively. It's a similar story with the Ford Fusion, Mazda3 and the Ford Mustang -- which all hung close to one another at 2.2, 2.2 and 2.1 percent, respectively. The Mustang's slipping, though -- with total sales falling from 16.117 during March of last year to 14,737 during March of '07.

* Around the number 13 slot, domestic-brand vehicles begin to bunch up -- with the Chevy Malibu, Dodge Charger, Chrysler 300 and Pontiac G6 sedan occupying 13th, 14th, 15th and 16th place. All saw their numbers go up slightly -- except for the Chrysler 300, which slipped from 12,901 cars sold in March of '06 to 11,376 sold during March of '07.

* After that, import brand cars snap back -- with the BMW 3-Series coming in at 17th (with 11,256 sold, a 1.6 percent increase over March of '06), followed at 18th by Hyundai's Sonata -- with another Hyundai, the Elantra, coming in at number 19.

* The last car to make the Top 20 in March was the Nissan Sentra. Recently updated, sales of this compact sport sedan came in at 9,654 during March of '07.
