Buying Tips for 2016 Vauxhall Mokka Mk1

  • Check the expansion tank and the whole cooling system for pink residue because small leaks are very common
  • 1.4 Turbo cars should boost cleanly without chatter or wastegate rattle
  • Dashboard and infotainment screens should all work because electrical niggles are common on family crossovers that live outdoors
  • On diesel versions, ask about DPF usage if the car mostly did school-run miles
