Rare find?

[procta]

That's pretty cool. The 'X' models are offered on the continent and in the States where they have cold weather long enough to justify the need for AWD. Over here some would argue (myself included) that our short-lived winters really don't represent a market for them, so they were never sold here afaik.

That appears to have had a LHD/RHD conversion at some point?

I wonder how easy it would be to get spares?

most of that you can pick up from a scrappy, ( if you can find a e36 in that shape)
the 4x4 system id have thought bmw them selves
