Sales of new cars and light commercial vehicles in Russia rose 13 percent year-on-year in March to 252,816, the Association for European Businesses (AEB) said.
The pace of growth was slower than the 25 percent rise seen in February.
The Moscow-based AEB forecasts an overall 12 percent rise in 2012 sales to 2.8 million, close to the pre-crisis mark of 2.9 million in 2008.
"The passenger car and light commercial vehicles market in Russia continued to show sustained growth in March though at a lower level than in the first two months of 2012,'' David Thomas, AEB chairman, said in a statement on Monday.
Lada continued to be Russia's top-selling brand in March with sales of 43,593, down 17 percent. Nissan is No. 2 with sales of 17,105, up 66 percent, followed at No. 3 by Hyundai, which sold 16,262 cars, up 30 percent.
Renault increased sales 17 percent to 15,524 to secure fourth place, ahead of General Motors Co.'s Chevrolet brand at No. 5 with 15,425, a rise of 11 percent.
GM's Opel brand also performed strongly with sales of 6,923, a rise of 39 percent. Sales of Ford vehicles rose 8 percent to 11,479.
In the first quarter, overall Russian sales increased by 19 percent to 614,273.
