Who is the most Jalop celebrity of them all? (pic unrelated)

Who actually works on their own whips, has impeccable taste (or not) etc. I want true A listers here, not reality show flunkies like Wayne Carini or Xhibit. Seinfeld, Leno, we all know about them, but give me more. Go deep, stuff like Tom Hanks and his Syncro Vanagon...
