Car sellers are blaming Brexit for a drop in new vehicle registrations.
Sales are down across all three counties in the north west:
New vehicle registrations in County Donegal have dropped by almost 10% — from 1,698 to 1,529 — this year so far, compared to the same period last year.
Sligo has dropped by more than 6%, from 714 to 671.
And in Leitrm, the drop was almost 16%, from 351 vehicles to 295.
The Society of the Irish Motor Industry says Brexit is the dominant issue with used car imports up 9.5% for the first quarter while new car registrations are down by 5.5%.
Total new car registrations in the country for the month of March were down 10.5% at 17,796 compared to March last year.
Meanwhile, new light commercial vehicle registrations were up 2% on March 2017 and up 5.4% in the year to date.
This, according to SIMI, reflects strong economic growth for businesses.
