Sales for the first half of the year were still significantly higher than those recorded in 2014, however, up 25.4% to 82,337.
More than a third of all car sales so far this year took place in January, according to SIMI, however the figures remained relatively strong between February and May.
Sellers will also be hoping for a mid-year boost this month, as the 152 registration plate is rolled out.

Of the 1,449 cars sold in June of this year, 18% were made by Toyota – making it the most popular car brand for the month.
The company’s Avensis was also the most popular model, with 90 units sold.
In the year to date Volkswagen remains the most popular make of car – taking a 12.7% share of the market – while its Golf remains the most popular with 3,807 units sold.

The majority – 71.2% - were also diesel fuelled, though this is down slightly on the same period of last year, with petrol models taking a slightly bigger share of the market.
More than 100 new cars have also been imported between January and June – up slightly on the same period of 2014.
Peugeot is the most popular make in this category, with 47 imported so far this year, while twelve Audis and eleven Mercedes-Benz cars have also been brought to the country.
