The Inverness-based firm, which developed out of a Victorian supplier of horse drawn vehicles, made an operating profit of £1.8 million before exceptionals in the year to December compared with £1.7m the preceding year.
Directors said the privately owned company had increased market share while retaining existing customers.
"This is borne out by an increase in new vehicle retail sales of 6.6% compared to the UK increase in new car registrations of 5.3% for 2012. Used vehicle retail sales were also 6.4% ahead of the previous year."
They added: "After sales service remained affected by the general economic climate."
However, the company signalled confidence in the prospects for the trade by acquiring the assets of a Honda dealership in Aberdeen in December.
The group has 10 dealerships in northern Scotland, trading in brands including Ford, Toyota, Jaguar and Landrover.
Directors wrote: "The balance sheet remains very strong and the directors believe the group is well positioned and intend to actively seek opportunities for investment within the retail motor trade."
The company made a pre-tax profit of £1.2m in 2012, compared with £1.7m the preceding year.
Directors said the pension obligation was transferred to an insurance company at a cost of £533,000.
