Language and regional support: If you prefer a particular language, pick a model that offers multiple languages. This is especially useful for non-English-speaking users or technicians working across regions.
Expansion and support: Some brands offer extensive DTC databases and ongoing updates. Factory support, warranty terms, and user reviews can help gauge long-term value and reliability.
