Buying Tips for the 2018–2020 Isuzu D-Max (Mk2)

  • Prefer the 1.9L engine (2017+) for ULEZ compliance and slightly simpler turbo setup, though it requires AdBlue.
  • On 2.5L models, listen for any whistling from the turbos, which can indicate impending failure.
  • Check the tailgate and load bed for heavy wear, which indicates a hard working life.
