Underside Sound Suppression?

[schuvwj]

Has anybody bought a sound proofing/anti-rust package for the underside of our MM's like Zbart, etc.? Did it help reduce cabin noise?
Was it worth the cost?

Laugh at the Lexus all you want. it is the quietest car I have ever sat in. And I have parked my keister in Bentleys, Rolls-Royce, Limos by the score, etc...
This little gussied-up Toyota is like riding in the casket, in the back of a hearse. It is THAT quiet. I would NEVER pay what it costs, however.
