Digi meter can be and is being turned back,from what i have heard costs 5k.
As for the car,ask him for the Japan report,the auction report should have the original kms done.
Also drive the car,the car says how old it is regardless of the meter and how much it has been used.
I had a Vitz which i imported,was a 2000 model but had only done 23k kms.The car looked and said that from the drive and look.
If the car looks good,drives well.then go for it.But yes if you can afford the new one then go for that.
