MGA Twin-Cam
The MGA Twin Cam was a high-performance car made from 1958 to 1960. It was really fast for its day, hitting 113 miles per hour. Despite this, it had so many warranty issues that pointed to serious design flaws. The engine would burn oil and even detonate because holes would form in the pistons, although there hasn’t been a reason cited for such a dangerous problem developing in the motor. After producing a bit over 2,000 of these, production ended.
