Why Free Scan Tools? Unmasking the Appeal
The allure of free scan tools is undeniable, stemming from several key advantages:
- Cost-Effectiveness: The most obvious benefit is the absence of a price tag. This is particularly appealing to car owners who prefer DIY diagnostics or want to avoid expensive trips to the mechanic for minor issues.
