Whether you should repair your own car or take it to a mechanic depends on several factors, including your mechanical skill level, the complexity of the repair, the availability of tools, and the time commitment. Simple maintenance tasks (e.g., changing oil, replacing air filters) can often be done at home by those with basic skills. More complex repairs (e.g., electrical issues, engine work) typically require specialized tools and expertise, making a professional mechanic the safer and more reliable option.
