I could not locate the owner of the car to ask about it, but the back seat was removed and he had pretty much the whole back seat area covered with the stuff. I especially liked the way he had it formed around the wheel wells and other odd shapes. Stuff kinda reminds me of the water-and-ice-shield mat they use for roofs in my area (Minnesota).
And now for the disclaimer: I have not used this product, nor am I affiliated with the manufacturer.
Specifically, the RAAMMAT BXT and Ensolite products. Laid down the RAAMMAT for sound deadening and the Ensolite for sound absorption. Put it all round and covered it all with thin insulation I got at Home Depot that is used for air ducts. I used this stuff because it was cheaper and I found good reviews on it.
Insulation over top of the RAAMMAT:
Ensolite on top of both:

Dynomat is another product that has been on the market for quite a few years. There are several others on the market as well. I used Dynomat in my '89 Honda Accord and it was as quiet as any of my big Mercedes.
