• Portability: As a mobile mechanic, you need tools that are easy to carry. Compact sets with storage cases are ideal, but ensure they still cover the sizes you need without being too bulky.
• Vehicle Compatibility: Check if the set is designed for specific brands like Ford, GM, or Chrysler. Some kits include specialized tools for certain models, which can be a major advantage if you work on those vehicles often.
