let's put it this way, I was able to find parts and service for a pair of Alfa's and a Fiero, neither of which are popular for mechanics to work with and Alfa has been out of the country for a LOOONG time,
(yes, I realize they're supposed to be coming back but I don't think the dealers who would service them would even recognize an older Alfa, they're only concerned with selling pricey Ferrari/Maserati alternatives)
The beauty of the VX is that there are a good many pieces which are common to other Isuzu products (save trim pieces), so I'm not terribly concerned about parts availability
However, with that said, if this is your only car I would consider getting something cheap to do the majority of your driving, both for our piss-poor gas mileage and also to keep the miles of the VX and needlessly have to look for parts if you can help it
