read theri ratings chart it explains everything and what rating means what. But do keep in mind Pakistan ppl do dealings in Japan too.
As for ppl selling cars in Pak, I do not think they can cheat you unless you want them too. if they show you a car and let you start the engine and see everything in it. I do not think that is cheating, that is honest business. The person is showing you the car "as is" if you like it you take otherwise you can walk away from it.
I was selling one of my cars and to a friend (I thought he was one) I just handed him the key and he said he will get it checked, i said good. After few days he comes back and says he is not interested, I said good. but after a few days I hear from my other friends that he says I was cheating him and giving him a damaged car. This is after I handing him the key and he disappears for a few days with the car and gets it checked and all. So after is this how cheat someone, by giving them full authority to satisfy themselves and still be called a cheater. I do not think so!
Morale of the story if a person shows you the car in and out I do not think that is cheating. Unless he just shows you the car and demands advance payment, then be careful.
there is twist to what happened to the guy after he returned the key. He really got ripped off by a rip off. he was sold a WRX as STI and over paid for everything and is now in debt for $20,000. That is being cheated!
