Certainly does look cool, but VW hasn't garnered any new fans of late with their poor reliability and assembly. I used to work on and restore air-cooled VW's about a decade ago and always enjoyed the level of engineering and craftsmanship on 'em, but as someone who came very close to '02 GTI ownership before the VX, I can say that quality is barely there anymore.
Isuzu knows trucks and has been engineering and building them for almost a century, far longer than Ferdinand ever thought of a People's Car. Isuzu is considered THE diesel engine manufacturer, which is a testament to building a good product. Yes, they don't know how to retain a good marketing firm and also let GM bully them around, but then again maybe they really are just content to build heavy-trucks and may only tinker with the consumer market.
In any case, Isuzu makes a far better vehicle than VW has in quite some time. Think of how many Trooper, Rodeo, Amigo, P'up, VX etc. owners there are with 100,000 plus miles (many offroad) compared to VW's of the same vintage. They are out there, but in fewer numbers with higher priced and more difficultly serviced parts. So, yes, a very cool looking concept. But if it was sitting next to the VX and both had 100,000 miles on the clock, I'd take the Isuzu.
