Mr. Wahab,
I think when it comes to getting the auction sheet verified, you are horribly misinformed. One can get the verification done online in a blink of an eye for a period of three months from the date of auction and that too free of charge. The only condition is that the car should not be more than three months old from the date of auction. That is how long the online record of auctions is reachable online. If you want to speed up things, just go to the port, select the car you want to buy, contact the owner and ask for the auction sheet. Go to the thousands of auto websites in Japan, punch in the lot # given on the auction sheet and bingo, there you go! You will see the whole car, its authentic mileage on the clock and its auction grade, virtually everything! You can also choose to pay the duty and the CIF by talking to the owner. Normally, you pay an extra Rs. 50,000 plus the landing cost of the car (CIF, cost insurance freight, duty and taxes, port charges plus 50,000 present to the owner!).
The only catch here is that the car has to be less than three months old from the date of auction when you make the deal and if you go to the port that is not a problem at all. You just have to be knowledgeable about how to get things done and and you will definitely get a very good deal.
One more thing; if the car is more than three months old, you ask for the auction sheet from the seller, fax it to the auction house in Japan which auctioned the car and they will verify it for you, i.e. whether it is real or forged. If the seller doesn't provide you with an auction sheet, you simply don't deal with him and look for the route I've just outlined for you.
Thanks.
