You lucky son of bitch!! That would be Mike's Z (gurneyeagle here on the forum). He has taken incredible care of it and has done a lot of very tasteful and functional mods. Enjoy it!
FWIW, the GTmat is better at vibration dampening than noise. I installed their Onyx product in my hatch. Get some closed cell foam to go on top of the GTmat if you really want to reduce noise. Tires also make a big difference if you value quietness over performance.
