All great advice here, as usual. That's why you came here MJJ. If I were you, get as many rides in any of our cars as you can, all the different makes as well. Having your own built is the way to get what you want, but wait time, cost, etc. Is never what you think it is, just times it by 3, and you will be close. I would buy used (Great time, market is full of them) spend a year or so, and make up your mind then. You will see if you are a Cobra guy by then, if brought right you won't lose any money, and will have a better idea, what your perfect Cobra will be
And worse case, you just spent a year driving a Cobra, I can think of worse thing's to spend a year doing
Cheers Tom.
