A surge in economic activity after a drawn-out election may reduce the fall in Turkey's domestic vehicle sales to 10% by the end of the year, the head of the local automotive industry association has said.

Car sales had declined 18.5%, general secretary Ercan Tezer told Reuters on Thursday.

"We have been seeing demand being postponed since last year ... If the demand we have seen in August continues we can expect to close the year with a year-on-year decline of 10%," he was quoted as saying.

Sales rose some 16% in August, normally a quiet month, in a sign demand was returning after a parliamentary election in July and presidential vote in August, he told the news agency.

According to Reuters, Tezer said vehicle exports this year were expected up 39% year on year to around $US20bn and would rise another 15 to 20% in 2008.

Turkish exports include Toyota's Corolla Verso minivan and the Ford Transit Connect commercial van. Renault and Fiat models are also produced in the country.
