Every bit of information has it's source, I cannot see any difference in finding the answer in a book, a magazine, on the web, or making an inquiry to solve a puzzle. Most puzzles have been solved by people who got their information from other sources, it's just that Pnegyesi is (to my knowledge) the first to admit he asked someone else.
Since he has found out more about the car than I knew, I think the point is well earned.
My source mentioned that he was waiting for approval to get it road legal. Do you know if he succeeded in doing so?
