One of the attributes of a Cobra is that they are "tinkerer's delight". There will always be something loose or in need of adjustment. As some say, even just sitting in your garage.
If you want something you can drive, park, drive, fill with gas, drive, have someone change the
oil, drive, park, etc. then buy a new Mustang. If you want something you can sink untold amounts of money paying someone else to do services try a Ferrari. But if you don't want to work on your car as much as you drive it, don't buy a Cobra.
