Pendragon posted narrower first-half losses on Tuesday, benefiting from lower costs and expenses even as revenue halved because of COVID-19 shutdowns.
The company returned to profitability in July and August, helped by a strong performance since the easing of COVID-19 lockdowns.
Pendragon operates the Evans Halshaw, Stratstone, Pinewood and Car Store brands.
The company said it remained unable to provide a full-year outlook because of uncertainties once the government withdraws its industry support programs.
"We have been encouraged by the first few months of trading after reopening and, while the outlook for the remainder of the year remains uncertain, we are confident the operational improvements we have made leave us well-positioned for the long term," CEO Bill Berman said in a statement.
Pendragon posted an underlying pretax profit of 7 million pounds ($9 million) for July and August, compared with a loss of 12 million pounds in the same period last year. For the first half, its underlying pretax loss narrowed to 31 million pounds from 32.2 million pounds a year earlier.
Pendragon said the pandemic would cost the company 44.1 million pounds this year.
Berman this month laid out a new strategy for the company to transform automotive retail through digital innovation, with its cloud-based dealer management division at the heart of the strategy.
The global health crisis has compounded troubles for UK car dealers, which were already facing muted demand and pressured margins after Britain's decision to leave the European Union.
The company had already announced plans to cut 1,800 jobs and close 15 loss-making stores as it dealt with pandemic-induced disruptions. Rivals Inchcape and Lookers have also taken similar measures.
However, Berman remains upbeat and told Reuters there has been increased demand for used vehicles as customers avoid public transport in the face of the pandemic.
Pendragon is Europe's fourth-largest dealership group by revenue, according to Automotive News Europe's 2019 Guide to Europe's Biggest Dealers. It has 177 new-vehicle franchise points in the UK.
