"Rules, Part 2: Posting links that compromise the integrity of other puzzles.
It is incumbent upon the poster of a puzzle to declare an answer correct. Sometimes, members like to post the links to sites where they have found the answer to a puzzle, in an attempt to offer “proof” that their answer is correct. While this may seem harmless, it has also compromised the puzzle sources of many member who cannot afford to purchase expensive volumes of automotive history."
Neither of those sites are in any way related to how I found out about the car - neither do they compromise, influence or indeed give any other information about any other vehicle.
