You are right, there is no fixed price for auction vehicles. But prices at auctions, don't fluctuate wildly. If a 5 grade car is selling for 100,000 JPY then all cars of the same grade will sell at more or less similar prices. The price cannot go from 100,000 JPY to 50,000 JPY for two vehicles of the same grade. If something is selling for 50,000 JPY, then obviously the grade is much lower than 5.
Forget about auction sheets when you are buying a Japanese import, 90% of them are fake and useless pieces of paper. Do you even know how to read a Japanese auction report? Unless you know someone who can get the auction sheet verified online, it is useless.
I bought a Mira Custom 2010 several months back. Along with my mechanic, we checked more than 20 cars from all over Lahore and all of them are accident repaired. 80% of the Japanese imported cars sold in the market are salvage vehicles which have been repaired locally, which is why you can get a Mira es 2012 for 10 lakh 60 thousand, may be even less, depending upon how major the damage. But that does not mean that all these cars are crap. You can still find a good vehicle without any major damage. The poster who started this thread also claims to have bought a repaired vehicle.
But if you think you are buying a 4 or 5 grade vehicles in this price, then the only person you'll be fooling is yourself. If you want to know more about Japanese imported vehicles, these two threads will serve as eye openers.
