New car sales in November were 20% lower than the same period last year, while sales for the first 11 months are up 17% on 2015.
The figures from the Society of the Irish Motor Industry also show 146,175 new cars have been sold so far in 2016 – a rise of more than 20,000 in the year to November last year.
Hyundai is the top selling brand, followed by VW and Toyota.
The most popular model of car sold in Ireland so far this year is the Hyundai Tucson, with the VW Golf coming in second.
Light Commercial Vehicles (LCV) have seen an increase of 8% when compared with November 2015 (620) and are currently up 19% (28,001) year to date.
Meanwhile, Heavy Goods Vehicle (HGV) registrations are up 33% year to date (2,844) but have declined 9% for the month of November (71).
SIMI Director General Alan Nolan said: “2016 has seen the highest levels in new vehicle registrations since 2008, even with the challenges of Brexit in mid-year and the slowing down in the last couple of months.
“Overall it has been a good year for our Industry and all indications look that registration numbers are on track to deliver in the region of 147,000 this year as predicted,” he added.
