Never seen even numbers on a German car past M10
6 8 10 13 15 17 19 21 Never seen a 14 or 12 on either Vdub Bimmer Merc or Porsche
Now off course on a Citroen.. they will use the entire range.. in ares where all identical nuts could have been used.
The front wing for instance on a DS will be affixed with something like 11 15 12 14 15 13 14
And all of them will be so rusty they round out on first attempt.
