British new car registrations rose by roughly 11% year on year in July, according to preliminary industry data.
July was the first full month that showrooms were allowed to reopen across the United Kingdom, as lockdown measures eased.
Dealerships reopened their doors to customers on 1 June in England, 8 June in Northern Ireland, 22 June in Wales and 29 June in Scotland.
July would be the first increase since December but year-to-date demand is down around 40% and the latest forecast predicts a full-year drop of around 30% in 2020.
In March, demand fell 44%, in April by 97%, in May registrations were down 89% and in June they fell by 35%, according to figures from the Society of Motor Manufacturers and Traders.
