The fact that there hasn't been a rush to build NB's for C was taken into consideration during ITAC discussions about the Golf. They are both close enough that the question becomes "perhaps too light in B or a fat-ass in C?" Consensus was that since the latter approach with the NB didn't seem to set anyone on fire, we'd lean the other direction with the Golf.
Not having any direct experience to call on, we presumed that the Golf follows current industry practice of simply piling more junk into a similar steel box as previous versions. Regardless, the ITAC is currently willing to accept that a too-low minimum weight might result - one that's REALLY tough to get to - if that's what the math says it should be.
At this point, the only reasons I'd go the MKIV route would be similar to those I considered when choosing a MkIII over a MkII - it's a generation newer so the parts stream will be longer. I wonder too (based on my experience now w/the MkIII) if the IV's share the awful rust problems we seem to be stuck with...

Yeah - it seems like for some of the options we're asked to list, there's no really good answer.
We can go heavy one way or light the other, but with the "tweeners" there are as many good reasons to NOT choose one course of action as there is to choose it. The MkIV tipped the scale one way, the Protege the other - based on the best information we had to work with.
It's impossible to know the Truth before someone an example of a new car, and frankly still really tough to sort the facts from fiction AFTERWARD. (See also, "1st generation MR2")

EDIT - And please remember that my comments about the ITAC as a body are filtered through my perceptions. I cannot see into the souls of my fellow committee members on a conference call. Recognize too, we work toward consensus decisions - one definition of which is that EVERYONE is a little pissed off about the final answer.
I agree with Kirk.
The MK2 has not gone the way of the MK1 at this point. The MK2 is right there. In New England region there are MK2's that win and beat the MK3's consistently.
From an investment point of view, avilability of parts, and longevity - one would not consider an MK1 platform for ITB at this point. If the price is right then an MK2 is a great way to go. Some of the stuff you can move over from your MK2 to an MK3... struts, rims, etc. The MK3 will hold it's value longer if there is such a thing in a race car then the MK2.

... You can actually buy almost any part including floor panels which we did for the current one we are building.
