The other day someone pulled up next to my 1967 911S, got out of his car and told his passenger "That's a European delivery '67 911S." He was correct but I didn't get a chance to talk to him and I'd like to know what he saw that made him say that. The obvious answer, to me, would be the tail-lights but the car has US type tail lights. What else could he have seen with only a glance at the rear and driver's side exterior to make this claim?
