probably because,

1) Isuzu is all but dead in the US until 2007. GM made sure of that.

2) While the VX might have inspired other "wannabe" its still completely different from them all. Only in styling is it similar.

The VX is true body-on-frame construction. Substantial V6 powerplant. All-wheel drive. Solid rear axle.

Whereas the Rav4, the Lexus Cute Utes are Unibody, car powerplants, IRS, two wheel drive.

The VX doesn't get the gas mileage a vehicle its size should. It weights alot and is driving that AWD which most village idiots don't need.

The one vehicle that I think most resembles the VX these days is the mercedes M-class. Its almost identical in performance and handling, although is a lot more comfortable on a bumpy road. I was considering buying my poor mother's M class from her until the VX I wanted practically showed up at my doorstop.
