I may highly recommend this make of speedos.
We use them on our Diesel motorbikes. And the good thing is, that they make an individual scale for you if you want, e.g. from 0-160 Kmh instead of 0-220 Kmh. They are very customer oriented, and the quality is high. This things even stand any weather and the vibrations of our Diesels.
They are available in diameters of 48 mm, 60 mm and 80 mm. I think it looks quite cool, and as a central round instrument in front of you it is not distracting. No mechanic coupling, uses signal from vehicle (they help with that and have even programmed the versions for our motorbikes to 'understand' their signals).

Other versions than this one are available, with LCD odometer, daily km, average speed etc ...
And a black housing is not a big deal - or maybe even possible by MMB.
