Well I can't guaranty all the text as I didn't write much of it. The article is Corvette specific so I think it’s OK that it only mentions others in passing. It was originally part of the Corvette entry. I’m not sure why it was decided to make it a separate entry. I do think that the Corvette’s implementation of a leaf spring is different enough from the traditional style that it deserves separate mention.

The Volvo 960 wagon used leaf springs for packaging reasons.

I really don't know much about Fiat's use of leaf springs. If I recall from, which I'm not doing well in this case, the Fiat use a metal leaf spring as both a spring and upper control arm. I have seen this on golf cars recently but I'm not sure about on road cars.
The GM W-body cars were cars for the North American market based on the "W-body" platform.
I partially agree with the point on perception. I would strongly argue that there is a perception gap. One has to look no further than the comment on the suspension when Top Gear reviewed their first C6. However, you are completely right that perception is not a technical point one way or the other. With that in mind it would be OK to pull the point.

Again, while I have edited the article in the past, as a Wiki entry no one person it 100% responsible for an article and anyone can edit it. My biggest concern is making sure people understand what I was trying to illustrate with the images. However, I'm also open to other feedback. And of course, anyone is welcome to edit the article themselves.
