12K miles in 4 years and never been stranded.
Get a AAA card and make sure you have a cell phone and a credit card whenever you take the Cobra for a ride.
The more miles that you put on the Cobra, it will be just like taking your daily driver for a ride ... except for the BIG grin on your face and all of the honks and waves and "Nice Car" comments.
Don't sweat the small stuff. Go for the gusto. I'm going to take off at 3 PM to go to a cruise night that starts at 6 PM. Have to get a nice 3 hour ride in before the cruise night.
