New vehicle sales in Thailand fell by 2.3% to 72,404 units in March, from 74,117 units a year earlier, according to a monthly report from the Federation of Thai Industries.
Consumer spending remained subdued as the country's economy continued to struggle to gain momentum after the 2014 military coup.
Last month's Bangkok International Motor Show failed to lift the market amid a lack of important new model launches. The show's organiser, Grand Prix International, said exhibitors reported just 32,571 orders this year – a drop of 12% compared with last year.
