According to Surapong Paisitpattanapong, the spokesman of the Federation of Thai Industries' Automotive Industry Club, said that the number was high though dealers have tried to encourage delivery.
He said that the net cancellation figure should be 100,000 units.
If dealers could not succeed in delivering the vehicles, it would be a great problem for them, he noted.
The scheme last year drew booking for 1.2 million vehicles. Buying vehicles under the scheme, buyers are entitled to tax rebates worth upto Bt100,000.
After the scheme ends, auto companies have attempted to boost sales this year through new campaigns. This is considered part of the reason why the cancellation rate is high. It is also on top of the declining economic condition, which sparks worries on the future of their income and debt burden for some buyers.
