I am sorry BUT this is not likely to be correct.
'Sterlingsilber, met.' was ONLY used for the 'Winkelhock' special edition cars (except for being an 'Individual' option choice).
The colour being used before 'Granitsilber-met.' on the 3.8 M5 was 'Sebringgrau-met. on the 3.6 M5 and probably on the
93 US-models but this should be double-checked *)
*) courtesy of bmwmregistry.com: For the final 1993 model year (starting 9/92 production), the North American M5 was given some cosmetic updates,
many of which were first introduced on the Euro-spec 3.8-liter model:
-Granite Silver metallic (237) lower aero panels in place of Sebring Grey metallic (229)
Pretty sure my black production 04/90 are painted 181 diamond black metallic.
Again as per bmw registry.com's faq.
In addition, the contrasting color of the lower aerodynamic body panels differed between the 3.6-liter and 3.8-liter M5 models. On the 3.6-liter examples ,these were painted either Diamond Black metallic (181) or Sebring Grey metallic (229). This changed with the 3.8-liter version to a choice of either Diamond Black metallic (181) or Granite Silver metallic (237). (Note: the change from Sebring Grey to Granite Silver also applies to the 1993 North American-spec E34 M5, which retained the 3.6-liter motor.)
