Flygirl, I think that part of the excitement in getting a Cobra is the mystery involved in getting and owning one, there is no such thing as a sure thing.
I have never met a Cobra owner that can't tell you a story or two of things gone wrong, or how things went great, it is an up and down relationship with your car. If this car is equipped like you want and you like the way it looks and drives, I would buy it, you will spend money on it, that is the life of owning a Cobra, there will be things break and things you will want to change as time goes on, but in the end you will love every minute of it and the fellowship of other Cobra owners helping and sharing there repairs and problems as well as the upgrades they have done.
As far as the
oil blow by, I think that is because of no PCV and no baffles in the valve covers, I know mine did not have them and I had to put them in to fix my
oil problem, it would saturate the breather and then little drops would start to fall out on the valve cover, installed baffles and a pcv valve and no more problems.
