Local car sales almost closed last month. Only 24 new car sales are listed, as the data shows.
The lock, which took effect in March, resulted in all showrooms being closed, resulting in a 99.4% drop in sales.
Unlike other months when they claimed positions in the top 3 most popular cars, there was no new Ford Fiesta or Ford Focus listed.
In exchange, the best-selling car in Northern Ireland was named by the Machine Manufacturers and Traders Company (SMMT) in April as “other Brits”, three were sold.
Three models, which occupy second place in the figures, each sells two. They are Dacia Sandero, Range Rover and Vauxhall Vivaro.
The other 15 cars are all one model, from Nissan Qashqai, Renault Clio and Lexus CT to two Audi A3 and Audi 6.
In contrast to the two dozen cars sold in April, 4,060 cars were sold in the same month last year.
Richard Ramsay, chief economist at Ulster Bank, said car sales in Northern Ireland had declined before the coronary virus exploded and stopped.
It is feared that the decline in demand for new cars will ultimately affect the number of jobs for large car manufacturers.
According to SMMT, which publishes a monthly report on car sales in the UK, sales in Northern Ireland have so far declined by 43% this year.
Sales declined in almost all of the UK in all regions last month, with 97.19% in the UK and 98.7% in Wales.
SMMT said the decline was the steepest in modern times and had similar disruptions in the car market in Europe, with a decline of 88.8% in France and a decline of 97.5% in the Italian market.
In Britain, only 4,331 new vehicles were registered that month – about 156,743 fewer than in April last year.
SMMT indicated that all new cars sold were sent to key employees, electricity companies and companies.
Mike House, CEO of SMMT, added: “With UK showrooms closed for all of April, the worst performance in the living memory market is hardly surprising.
“However, these figures are still very dark reading, at least for the hundreds of thousands of people whose livelihoods depend on the sector.
“The strong new car market supports a healthy economy, and with the UK planning to recover, we need a leading car dealer.
“Safely restarting this very critical sector and reviving what would surely be blunt will be the key to opening production and accelerating the recovery of the British economy.”
