I have a December 2015 Overland CRD, with additional fruit, yet to hit 10,000km. Is the third car so rarely used. Probably the lowest mileage completely Dealership log book serviced - averages 500 - 700 km each service. Every TSB, Service with FCA authorized mods.About 80% tread on original Michi - off road group fitted. Deep Cherry Red in garage with car cover.
Can no longer justify keeping only to pay insurance & rego, so going to place in the for sale section shortly...
Cheers
