Jis ki lathi ski bhains :). I have seen people being paid back by the dealer only case the person was influential or was related to the dealer (again had influence on the dealer at least).
At the same time, have seen people being victim of dealers. I also know there are dealers who are very fair and square.
With the big cars, one issue as far as I can see is that some are procured (not imported - but altered or without original files) by influential people and they are able to make a jugar with papers (not always but only in some cases) and by the time you realize this you already are stuck with the car/jeep.
It is best to clarify the papers before you buy the car at the source, i.e. if the jeep is registered in Lahore get the papers checked in Lahore. I think the paper checking and process of buying cars has improved a lot.
Get the car/jeep checked by an experienced person no matter which one you are buying and it should be ok.
