Paul,
It appears that you have a really nice aluminum Cobra which is actually worth a lot of money in its own right (if it was done correctly and not abused)
In the future when you are selling any car, whether it be this Cobra or a 1990 Ford Escort, do yourself a favor and only state the honest facts. Your buyers will appreciate it and you will sleep better at night.
That goes for all of us, not just you.
I don't mean to preach, but I (like a lot of us) have purchased things that were not as they were presented and really felt cheated and used.
Enjoy your Cobra while you have it. It looks really nice.
