Talk:General Motors proving grounds

Coordinates
Please note that the coordinates in this article need fixing as: The coordinates published are actually those for the Millbrook Proving Ground in England, not the Cupuan (Mexico) proving ground.
 * This seems to have been fixed already. Deor (talk) 02:54, 15 April 2009 (UTC)
 * The coords for the new facility in Yuma are missing, while the coords for the old Mesa location are still there. -- 208.81.184.4 (talk) 22:42, 8 June 2010 (UTC)

Dudenhofen
There is an Opel test facility at Dudenhofen, Germany (49.9927777778N, 8.92305555556W), so I've added a short section with a few details I managed to glean from Opel's website: http://www.opel.de/meetopel/opelag/location/dudenhofen/index.act. Anyone with a better grasp of German than me should feel free to expand it.Mr Larrington (talk) 13:48, 10 June 2010 (UTC)

Millbrook no longer under GM Leadership
Millbrook is no longer owned by GM, it was sold off to Rutland Partners late last year. I guess now it will need its own page?

Milford Proving Ground
Is there a citation that can be used for the comment that one mile driven on the grounds is the same as 5 miles in the real world? Sleepmags1 (talk) 15:44, 11 September 2020 (UTC)
