If you pay money for it, it ain't free. Matters not to whom the money is paid. Each car is a cost centre. Each cost centre is balanced against the wish/need to own. I have never seen a 'free' car. They do not exist in reality.
However free storage with a car gifted is very cheap, and can remain at a peppercorn cost per year, unlike the rental of, say, a council garage. Over 10 years at £12 a month, say, that would put the free car at a cost of £1,440 plus getting it home - so call it £1,500. Do I want a dead Powerdrive for £1,500? Some may, some may not and ownership of the rare is the only way to secure one. However I would not call this a cheap car but probably about the right value now.
Meanwhile Mr Woodland has had the pleasure of being able to gamble round his woods, with grandchildren or pigs, full in the knowledge they will not be hurt by a derelict car such as the one Dave bought for £50 with my help years ago, since hardly anyone was remotely interested in Powerdrives. It all seems logical to me. But then many folk choose not to produce real costings on their hobbies and vehicles as the real figures tend to make the eyes water a little more than the theoretical ones.
None of this has any bounds on county, creed or purchase. It is logic and reality. It is how to know if you really made any money out of a car, or other thing, should that be important to you. It is to me and I know the cost of each of my cars pretty accurately, therefore making clearance and disposal easier as I can judge when a car is in danger of exceeding its level of value, or if I invest in it as I like it, how much I stand to loose so that I am sure I gain enough enjoyment from it to warrant the overspend unlikely to be recouped. I seem oddly unusual in doing this from what I can make out.
