I said "approx" 5000. The FIA makes you produce enough spares to actually market and service the "production" automobile in order to qualify for that class. As far as the VX-4, do you remember Isuzu's XU-1 concept/show car? It's a four door extremely advanced styled vehicle, that would never go to production. The VX-4 is no different, just like the convertible VX-02, it's just a for instance type message vehicle, not for mass consumption, a custom one off, to gain more Isuzu press, that's all.
