Flick,
Welcom to the madness. You don't have to be a mechanic to have one of these cars. They , like all vehicles require maintenance and more than the normal car does. A lot will depend on how far out you go so far as a radical or calm motor, how you drive it, and just what you want to use it for. A normal daily street Cobra with a nice 300/375 horse motor won't require a huge amount of maintenance other than the normal stuff.
Oil checks, water, that kind fo thing. And any question that you have, there will be someone here that can help you with it. It took 4 of them a year to finally convince me my motor was in the front of the car.
Oh, and don't let the BB guys convince you that is the only way to go.
