1971 Porsche 914/6 Paint Colors & Codes

The chasses for the Porsche 914 and Porsche 914/6 model lines were identical. They were all produced by Karmann in the same factory. Subsequently, the color choices for the Porsche 914 and Porsche 914/6 models were also identical, although Porsche assigned different paint codes to the 914/6. These Porsche-assigned codes all ended in "10," denoting the black (Targa) roof. Not surprisingly, this alternate paint code format created confusion, resulting in the decision to standardize on the VW paint codes being used for the four cylinder cars. This change occurred during the 1971 model year production run.
