We have this in Manitoba, Canada, too. It can work for you in some cases. My 1980 Cutlass sedan with a 403, TH350, and IROC rear end cost me $1600 certified safe (asked 2500). When I registered it, they looked my receipt and told me the tax. I replied that suppose I didn't have the receipt, then how much is it worth? 100 bucks, she said, is all that they would give me in a write-off (sounded like wholesale scrap to me). I asked for a blue pen (small-town friendly) and holding it over the "1600" on the bill, asked, "How is sixteen dollars?", and she said, "Better make it a hundred and sixty". Like they are going to scrap it anyway. That's my job!!
