I believe 4153 VX's were imported to the US during 99, 00, and 01.
.
I never have been able to locate production numbers for other parts of the world.

Unlike some/many other limited production vehicles - that are barely used - the VX's do see alot of 'action' - are used as daily drivers and for recreation. Because of this, a number of them have already been 'retired' ..... (ouch).
