DIY car servicing is a great way to save money and reduce your car's maintenance costs. However, unless you run your own garage, I think it would be unrealistic to expect a buyer to pay top money for the vehicle and accept your skills and expertise at face value. That's why DIY servicing is usually favoured by people who intended to keep the vehicle for the long term.

Few people outside of the trade have the professional skills to service and maintain a modern car. As a result, in my experience, cars with no service history tend to be in a poor mechanical condition.
