Owning a classic car can be an excellent experience in many ways. First, you own a car which is no longer produced, but people admire. Second, most classic cars do not have the electronic nannies that exist in today's cars, which often leads to a more direct and raw driving experience.
However, as mentioned in the first article in this series, it is important for one to get a Pre-Purchase Inspection. This is an excellent video, from Drive Clean, which goes through the details of a PPI on a 964 Porsche 911.
Even a PPI may not show everything that may need to be fixed on a classic car. For instance, before the advent of modern computer systems, most classic cars used relays. A relay is a type of electronic switch and can be prone to failure. If a relay fails, the many of the electrical systems of a car may not function. For instance, the headlights could not work, or the car could not start.
Also, many classic cars do not have modern ignition systems or have rudimentary computer systems. Some owners consider this a good thing, while others do not. With some cars, such as the Porsche 944 Turbo, having rudimentary computer systems can be difficult to diagnose problems. In addition, these cars use a distributor cap and rotor, which can lead to ignition issues.
Sometimes, problems can be difficult to diagnose, so it is important to have an excellent technician that specializes in our specific make and model.
