This listing in that ad caught my eye:
SALE PENDING - 1974 Europa JPS (“Johnny Player Special”) (Converted to Weber Head and Carbs in 1976, original owner, not black/gold colors)… $18,000
Interesting that he converted it to a Weber head but it's not black/gold? What color is it now? Is it REALLY a JPS? There didn't appear to be any pictures of it...
