Toyota's affiliate Daihatsu is ending the 10 year run of its Copen model, the only convertible minicar on the Japanese market.

The carmaker said it will stop making the roadster following poor sales in recent years. Production will cease at the end of August.

The Copen was launched in June 2002, winning a Good Design Award that year, and sales peaked in 2003 at 11,000 cars. Last year the company only sold around 2,000 bringing total production since launch to 56,000.

Honda and Suzuki also sold convertible minicars but they ended production some time ago. Daihatsu said it will roll out 500 special edition 10th-anniversary versions before the end of production.
