I know you're probably getting a lot of advice behind the scenes, but try to understand that these cars aren't for everyone. You may very well find it is the perfect car for you, but, until you drive one you really won't know for sure- as many of the previous owners have found out the hard way after spending lots of money and countless hours building or searching for one.
They have lots of power and handle wonderfully, once set up properly. But Cobras are, by nature, small and cramped inside, have few amenities, and the sidepipes are loud enough in your ear you probably won't be able to carry a conversation with your wife while driving. (for some of us that would be blessing)
These aren't like any "European" car you've ever driven, I'm quite sure.
Some Cobras are more cramped than others, which is why some guys suggest driving a few before you decide. Hopefully, you are not only looking for cars with your short list of requirements, but also take the time to sit in a few (drive if at all possible) and see how they fit you and feel when driving hard. You don't actually get into a Cobra as much as you put it on like a suit. Then, there is the inevitable 2-4 minutes of buckling up the harnesses and making sure you (and your passenger) are strapped in tight. Then, you have to watch for the sidepipes so you don't get a "snake bite" on your leg as you get out of the car with hot pipes. You'll have to park it somewhere you can watch it so the hordes of admiring people don't lean against it, scratch it, or let their kids stand on the sidepipes or sit in your car. (everyone here who owns one has had all these things and more happen).
Good luck in your search. Hope you find the exactly what you are looking for. I'm looking forward to see what you finally come up with.
