As for not being in the 80s. Actually this rifle is from the late 80s. I love bullpups but there are some ergonomic flaws with this one. Flaws that either don't exist or have been limited with the Modern military bullpups such as Tavor, FS2000, PS90 etc.
But it comes down to wanting/collecting. Frankly unless the price was a huge bargain like the infamous Type97 saga, then it's not going to appeal to the average shooter. There are other alternatives around that price point which are well known. Plus there are also cheaper alternatives.
I think your Jaguar analogy really hit the mark.
