Anecdotal but from a reliable source. Some of info is public knowledge.
"Adam had a few Astons. Indeed I think it was in a DB5/6 that he got busted for possession of weed outside a Dublin mountains pub many years ago.
Clayton had a huge collection. Various Lamborghinis etc. He sold most of his rock star cars as part of his sobriety journey. "Anything I couldn't remember buying" iirc. I once viewed a BMW 2002 in green that was said to be an ex-Clayton car . Xxx-666 reg on it. It was in very poor shape, so I passed.
Bono had a w116 Merc in the 80's with cow print black and white seats. Also owned a few Bristols, one was brown. Horrible thing. He also had a brown Quattroporte. In the early 90's he had a Vicarage Jaguar MK2. Kind of an early resto mod. I met him once at The Factory recording studio in the early 90's and he was driving a yellow Mk3 Cortina in yellow, black vinyl roof and leopardskin seat covers.
For many years, his wife Ali drove a high spec, non-GTI MK2 Golf 5 door in white. A GLS or something. It had the big bumpers of the GTI, but not the stripes and spoilers.
Edge seems to have mostly driven w108 S-class cabs and coupes.
Only car I ever saw Larry in was a maroon MK2 Golf CL. He used it as his airport car in the 90's. He always preferred bikes anyway."
To add to the above, Larry was photographed on his way to or leaving Adam's 2013 wedding driving what was obviously a Merc (you could see the three-pointed star on the steering wheel from the photo - don't know what model.) I was told Adam was seen in the 1980s driving a Citroen SM, a rare car, near where he lives in Rathfarnham.
