Michael, my 2 cents worth...
It sounds like you already have the fabrication skills and the motivation. If you have already built cars in the past, then you know the amount of effort it takes to keep pushing yourself to finish a project.
Like you, I was sick of doing rust repairs, so a Cobra was a very attractive option.
Anyone with a cheque book can go and buy a finished car, but only someone who either has the skills, or wants to learn, can build a car. The satisfaction of being confronted by a problem and then working out a way to solve it, is one of life's great enjoyments.
If your kids want to get involved, then what more reason do you need?
There are dozens of very experienced builders on these forums who are always happy to pass on their advice if you are stuck.
If you want to know what each part of the package you are buying consists of, then ask the person you are buying it from.
I am looking forward to seeing photos of your progress.
Regards
Will
