While I will not presume to answer all your charges re: this article on "Scaring Away Reposessors", doctor evil, I ask your indulgence here:
First of all, the condition that financed property is kept in is hardly a concern of a lender when outright purchase of an item is involved, rather than leasing it: They just want your money. Otherwise, there'd be a lot more "repos" just because the buyer is a "slob", and a lot of repo companies would be "on the hook" for damages sustained during the repossession process, too.
Your contention that most financing is done with local companies, other than auto sales or real estate, who WILL grab any property financed with a security interest on it, just to make a point? How quaint! Way outdated, even for expensive items. Even smaller retailers these days either accept bank credit cards, or farm-out the financing to major companies; they just handle the up-front paperwork, and perhaps takes the payments as a "middleman" (seemingly rare these days). It's the finance company/bank that takes the risk, not the retailer which is paid for the items up-front. Would the "bank" want it anyway? Naaaa...such entities do not want the stuff, even if it is salable, because the expenses behind a repo. and subsequent auction are far too high for what they will get for almost any item...and this often INCLUDES automobiles, if the book value is low! In fact, it will, in nearly all cases, cost the finance company/bank more money than they will get to even attempt to do this.
As far as replacing an odometer is concerned? Well, mechanical parts do break down, and how would you prove that the original odometer was still functional if it is no longer around? There is NO law that requires a repairer to turn in the allegedly "dead" one to anyone, or retain such, nor is it required that the new one be set to the milage figure of the old one. Or, that such an item be brand-new when installed...it just needs to work. Nor would you be likely to be able to prove when the odometer was replaced. Nobody is required to keep detailed records of that, either.
If someone is really concerned about the effect a judgment will have on their assets and financial situation, they are hardly going to care about loss of resale value. In addition, any savings in the insurance area due to the seeming high mileage of the vehicle in question would likely be most welcome.
