New vehicle sales in Thailand declined by 3.5% to 111,848 units in May, compared with 115,943 units a year earlier, according to data released by Toyota Motor Thailand.

The weaker market in May reflects the withdrawal of first-time buyer incentives at the end of last year, as well as strong year-earlier data.

Sales of pickup trucks fell by 4.8% to 49,664 units, while passenger car sales were down by 5.8% at 52,734 units. By contrast, sales of other commercial vehicles - which were not significantly affected by last year’s incentive programme, were much higher in May.

In the first five months of 2013, new vehicle sales increased by 32% to 634,762 units, compared with 481,366 units in the same period of last year.

In the early part of 2013 the market continued to benefit from deliveries of vehicles sold under last year’s incentive programme, as well as the resumption of vehicle production at Honda in mid-2012 after it was devastated by floods.
