New car sales rose by 30% in 2015, when compared with the previous year.
The figures from the Society of the Irish Motor Industry (SIMI) show that the total new car registrations for 2015 stood at 124,945, while in 2014 the figure was 96,284.
December car sales saw a slight decrease, down 1.44% (342) compared with the same month in 2014, however, December volumes tend to be relatively small when compared with the rest of the year.
Last year, Light Commercial Vehicles saw a 42% rise in sales compared with 2014, with just under 24,000 vehicles sold.
Meanwhile, Heavy Goods Vehicle sales were up 9% year-on-year.
Commenting on the figurers SIMI Director General Alan Nolan said: "We are pleased that 2015 has turned out to be a good year of continued recovery for our industry, which is a very strong indicator of the health of the general economy.
“We now look forward to 2016 with greater optimism and a real potential to see registrations return to normal levels that we have not seen since before 2008,” he added.
SIMI expects the improvement in sales to continue in 2016.
