In the month, passenger car sale dropped by 24.7 per cent on year while commercial vehicle sale slid by 27.3 per cent, according to the data compiled by Toyota Motor Thailand.
"This is due to the persistently high household debt level as well as financial institutions' stringent lending criteria. This affected liquidity and consumers' purchasing power," said Vudhigorn Suriyachantananont, senior vice president of Toyota Motor Thailand.
Combined sale volume in the first four months of this year dropped by 15.3 per cent on year to 251,845 units.
