What is the paint code for Porsche 912 Slate Grey?
Slate Grey on the Porsche 912 carries the paint code 6404 — also known as Schiefergrau in German and Gris Ardoise in French. This code is stamped on the body tag located on the firewall and is the definitive way to verify an authentic factory Slate Grey 912. Any example missing this code may have been resprayed from another factory colour.
How much does a Slate Grey Porsche 912 cost?
Confirmed original-paint Slate Grey (code 6404) Porsche 912s command a 25–40 % premium over equivalent cars in common factory colours. Documented originals in good condition typically start at €55,000–70,000, with pristine concours examples regularly exceeding €100,000. Resprayed examples also carry a premium, though the gap between original and repaint has widened considerably in recent years.
How do I know if a Porsche 912 is real Slate Grey?
Check the body tag on the firewall for paint code 6404 — this is the only definitive proof of factory Slate Grey. Inspect door jambs, under the bonnet lid lip, and inside the luggage compartment for original paint remnants that match the exterior colour. Compare panel-to-panel colour consistency under different lighting; a factory original maintains near-perfect consistency. Many 912s have been resprayed in Slate Grey from other colours, so the body tag is essential.
