This is from Porsches site. I think it is for 2003.
Production Volumes increased
High demand during the review year led to increased production volumes. A total of 81,531 units left the production line - an increase of 11.3 percent. Of this total, 31,250 vehicles were produced at our main plant in Zuffenhausen, 41,419 in Leipzig, and 8,862 by our partner factory in Finland. The breakdown for the various models is as follows: we produced 26,650 units of the 911 model, including 3,432 of the latest model generation, known internally as the 997. As in the previous fiscal year, higher-value 911 variants accounted for a large share of this classic vehicle's total production - 66 percent to be precise, including the S version of the new 911 Carrera.
Boxster models remain in production both in Zuffenhausen and at our Finnish partner plant - a successful collaboration which will continue with the new Boxster. During the year under review, we produced 13,462 Boxsters; 8,862 of them were assembled in Finland.
In addition to the Cayenne - with 41,149 units - Leipzig produced the Carrera GT during the review year. The first 270 of the limited production run of 1,500 high performance sports cars have already left the plant.
