Bhai:
Sell your Camry and buy one in Pakistan! Your Camry won't be of much value in Pakistan. And no, you have heard wrong! You will still have to pay all the duties in Pakistan.
And you tell you the truth, more than likely, your Camry is built in the USA (if its VIN starts with a number; if the VIN starts with a J, then its imported from Japan). I have a US built Camry here in the US as well, and I can tell you that compared to the Japanese models, the US built quality is far inferior to that of the Japanese. My 2007 Camry squeaks and rattles everywhere.
The ones you get in Pakistan, are RHD and are built in Japan. NOTHING beats that.
