No, I do not expect any long-term impacts, as this was not a demand problem but only the dealer’s systems were temporarily out of service.
According to Cox Automotive, it simply created temporary noise in the data, and the sales lost in June are likely to be recovered in July.
They also indicated that initial numbers could appear worse than reality, as reporting delays due to the attack could have impacted reporting more than actual sales.
I think there was a misunderstanding. The shortage of new vehicles and consequently lower sales in 2021/2022 will impact the supply of used cars in coming years.
However, Cox Automotive still forecasts only a 1.3% increase of new car sales for 2024.
