As a previous VX (Vehicross) owner, it really tickled me to see them comparing the SSR to the VX! The VX got a lot of attention, was fun to drive and never seemed all that wimpy performance wise to me, but the SSR is miles ahead of the VX in every way. As a more-or-less standard Chevy product, the SSR will never be the orphan that the VX was within a few years, and the fact that every dinky little town has a Chev dealer whereas the Isuzu dealers are few and far between, means you can travel just about anywhere in the SSR without worrying about a breakdown.
That points to another advantage of the SSR over a hotrod/streetrod. I would never consider driving any of those hybrid/custom made outfits 500 miles or more on a vacation trip for fear of a breakdown. The SSR on the other hand will do just fine and I won't worry a bit about something breaking.
