  2. Transmission Choices: The Series III was available with either a 4-speed manual or a 3-speed automatic transmission. Both options were paired expertly with the V12 engine, offering both thrilling performance and smooth driving.
  3. Suspension and Handling: The Series III featured improved suspension components, including wider tracks and anti-roll bars. These upgrades enhanced the car’s handling and responsiveness, making it suitable for both leisurely driving and spirited performance.
