German car registrations fell an unadjusted 10.4 percent in August, due to two fewer working days, only the third monthly decline this year, masking otherwise stable underlying demand in Europe's largest economy. Official data published by the German motor vehicle department KBA showed registrations of new passenger cars fell to 214,386 vehicles last month, bringing the cumulative total for the first eight months to 2.11 million, a total rise of 1.7 percent. While significantly better than the performance in other western European countries such as Italy and Spain, the slight increase in year-to-date registrations was helped by a flattering comparison with last year, the German car market's worst year since reunification in late 1990.
