Getting in and out of it, with the accompanying butt crack, made my Cobra cringe regularly.
Asking Buckley why my steering wheel moved back and forth so much, and having him find the bolt loose on one of the knuckles, was somewhat embarassing--especially since I drove it that way over two autocross seasons.
Finding out that fuel cell bladders aren't supposed to be used for twenty years, which explained the weird fuel smell--that was a pretty good one.
Others...but you'll have to ask the Cobra for details.
