Glasgow-based Arnold Clark Automobiles, Scotland’s biggest privately-owned company, said its turnover rose 2.2% in 2015 to a record £3.35 billion.
Operating profit rose 1.7% to £121.7 million and pre-tax profit rose 2.2% to £110.3 million.
Used car sales soared 10.8% to 175,526 units.
However, new car sales fell 8.4 % to 83,813 units “largely a result of a large fleet contract that was not renewed due to the significant amount of working capital tied up in the agreement.”
Arnold Clark employs almost 10,000 people.
“In 2016 we expect that the new car market will remain relatively static, with used cars experiencing similar growth to 2015,” said chairman Arnold Clark.
“Funding remains in place to take advantage of any opportunities that may arise and to overcome market volatility.
“Early trading results have been very promising and out strategic objectives remain unchanged: namely focusing on customer experience, product availability and widening the geographical footprint of the group.”
