We have one here in (Sacramento) California you can have; it's not supposed
to be available for a couple more years but as far as I'm concerned you can
have it now.
It's getting kind of old and has been known to use illegal additives,
however it might be a good option for someone concerned with keeping their
van all German.
Caution: might cause steering problems; it may cause your van to veer
slightly more to the right than to the left, however it won't go far enough
either way to be useful or enable you to plan a course. May also cause
extreme credit issues for whomever owns your van in 20 years.

Cya,
