I think that you are correct in that as cobra owners, it would be nice for us to share our knowledge with potential cobra owners. I do not think that it would hurt the market, it might actually help the market. A totally uniformed buyer might get into something that is beyond his skill level and then sell off the car at a loss, thereby lowering the market value of cars. There then might be a run on selling cobras and we could start a new Great Depression !
Seriously though, when asked, we should share our knowledge when asked by people seeking knowledge as they go about contemplating a purchase. The person then has the opportunity to make a more informed decision. Similar to Phil, I spent some time researching my purchase and making comparisons. I not only researched cobras, but also cobra owners to get an idea about their credibility.
I think that as long as people are giving good faith perspectives, that the forum benefits. That is why a forum exists, to provide an opportunity for people to share ideas and perspectives.
