The real scam is that they use different book values to assess the tax on a sale vs the value of a payout if it's written off. There are three different "books" in Canada to obtain a value of the car; Edmunds, Kelly's Blue Book, and Canadian Black Book. You pay tax on the Canadian Black Book but should the vehicle ever get written off they use the Edmunds to determine value. On average, Edmunds values are half of the Black Book value, with Blue Book usually floating in the middle.
If the government states Black Book is the value of vehicle when it sold in BC that should be the only book they use; not choosing the one that to suit your themselves
