Shelbourne Motors has announced a pre-tax profit of £1.2m in 2018 - a 28% increase on the previous year.
The family-owned vehicle dealer said the rise in profits came from a strong sales performance in new and used cars, as well as after sales services.
The increase in pre-tax profits coincides with Shelbourne Motors' £5m investment in a new multi-franchise complex in Newry.
The 50,000 sq ft development will create 60 new jobs when it officially opens this month.
It will include new Renault and Kia car showrooms, a used car supermarket, new car handover bays, lounge-style waiting area and a drive-thru service centre with a state-of-the-art workshop facility.
