Please help me to identify this font. It was found in a Vauxhall Service manual from 2004, and think it's got a lot of character. Thanks!

Don’t know if Vauxhall is part of the OPEL corporation, but the typeface shown looks like the proprietary Opel typeface by Monotype. Similar: Metromedium#2.

Brilliant thank you!

Yes, it's Vauxhall in Britain, Opel in the rest of Europe.
