I can't foresee any issues getting parts down the road for Isuzus in general, and nothing more difficult than we already face for VX specific stuff. I've owned FIAT 124's, Merkurs and other unusual or briefly imported vehicles and never had issues locating parts. My first stop was always the local NAPA as they would often surprise me with what they had on the shelf, especially for FIAT.

Now consider Isuzu's constant presence in the US since the 1960's and you can imagine the stock of parts. We share the bulk of our parts with the Trooper and Rodeo which you can locate parts for virtually anywhere. But, on the other hand, for those panicky enough to bail on such thoughts should provide a glut of VX's for those who are resourceful and know how to use a parts counter.
