Buying Tips for 2020 SsangYong (KGM) SsangYong Musso

  • ✓Check the load bed for heavy damage; despite the premium interior, many are used for serious commercial work.
  • ✓Verify the service history to ensure the remainder of the excellent 7-year warranty is still valid.
  • ✓Test the engagement of the selectable four-wheel-drive system, ensuring it shifts smoothly between 2H, 4H, and 4L.
  • ✓Inspect the rear suspension; the coil springs provide a great ride but can sag if the truck has been permanently overloaded.
  • ✓Listen for a whining noise from the automatic gearbox under heavy load, indicating worn fluid or impending issues.
  • ✓Check the operation of the touchscreen infotainment system, as the software can occasionally freeze or lag.
