Well if you compare a zero meter Cruze with zero meter Mark X(or with some other similar category JDM car) that would be a better way to compare. A used 2007-2008 Mark X costs around 30 and there is no guarantee that the car has not been tampered with to be honest. At times very high mileage hit & repaired used cars end up in Pakistan.
Well before any new car is launched official 3s people get special maintenance training from company. The same also applies as far as other local manufacturers are concerned. So backup support is present, plus official Chevrolet dealers can provide parts easily. If if they don't have it in stock they can order and get it...its not that easy as far as used jdm cars are concerned(esp if they are rare ones).
