Ah, Diamond Dave in his prime.
As I recall, either he or the Van Halens had, at some point shortly after their eponymous debut smash-hit record dropped, a large four-door Mercedes Benz sedan with a 6-71 blower jutting through the hood.
I could swear I saw that thing on MTV, shot from the front with the whole band inside the car, obscured by that insane intake setup. But I can't find it on the innerwebs now...
It was probably this one; guessing he had the engine work done after he towed it off the beach.
So, full circle.
