I skimmed through an copy of 'Traps' magazine that features John Henry Bonham.

In the article,the author mentions Bonzo owning a Lamborghini-twice,actually. Once he mentions that Jimmy has called John's home and is told that he's not yet returned from the tour to Jimmy's surprise. But just at that moment,the rumble of John approaching in his new Lamborghnin can be heard in the distance.
This is the first I've heard anything about John owning a Lambo. I wonder what it looked like..what year and model.
