Drove the one with 64,000 on the clock and it was OK
Drove another with 82,000 on the clock and felt better. Both similar specs, the higher mileage was $6400 cheaper when the acc were taken into account and $800 dearer than the previous one with 120,000
The big deciding factor was that the better half liked to colour of the 82000 one and gave her seal of approval so it is a done deal.
Finished up with a 2014 XTR with nudge bar, ARB canopy, factory second battery, electric brakes, tub liner, tow bar, two anderson plugs new Khumo tyres and tinted windows. Very happy with the service history and the way it drove.
