Totally agree with Hannan. The article is somewhat overrated. Although I appreciate the warning sounded by the original poster about imported cars in Pakistan, the photos shown in the post are of major accidented cars and I think vast majority of imported cars are not damaged like this.
My experience with imported cars since 5 years now is simply superb. The local 'teen dabba on wheels' cars are a piece of junk as compared to cars actually manufactured in Japan, one of world's most advanced nations. Their safety and quality standards are simply way, way above that of 3rd world countries.
Secondly, there are some simple tips for buying imported cars, as highlighted by Hannan. For example, buying from credible dealers, even better if through some reference or acquaintance. I think there are auctions at Karachi port by bulk importers and if one can visit the yard, one can pick a lightly accidented car for sure. Other than that, there also must be ways to look for a genuine auction sheet, which tells it all. Some dealers also give the option of viewing a car directly on a Japanese auction site to select and bid. And of course you can view their genuine auction sheet there. Of course you can also have a reliable denter/painter with you who can tell about replaced parts of the body and one can then cross check if they are reflected in the accompanying auction sheet or not. If not, then its a fake auction sheet.
These are just some ideas from me. If you guys have some more tips to share with others on how buying imported cars, do share for benefit of all.
