Unfortunately this makes me think of 1950s America, where the BIG 3 decided to go for "built in obsolescence" on their ranges, which meant that people were forced to buy a brand new car every three years as a) to keep up with the Jones' and b) their car had just fallen to bits.
I have 4 cars in the household at the moment, one of which is in excellent condition after 33 years, two are in great condition after 13-14 years service (and over 330,000 miles between them) and the most complicated on is now 7 years old with nearly 200k miles. I won't be chopping any of them in any time, ever. Perhaps I am lucky in that I have found 4 cars that are not really money pits (touch wood), but I find these schemes to be extremely short-sighted in terms of total cost of ownership.
One comment earlier on a different thread read something like "I'd chop mine in for £7k any day", but made no sense to me as you'd have to buy a £30k+ car to get that kind of money, then lose that £7k virtually as you soon as you drove it off the forecourt. Maybe it's my age and upbringing, but I am pretty averse to the idea of not actually owning cars (PCP schemes etc), but again this seems to be the way that the car market is going these days. They are disposable items that you rent for a few years, then throw away and forget about whilst you move onto the next new thing.
Personally, I have never once bought a brand new car (my wife did once buy one, but it was a cheap Seat Arosa, so not a lot of money to lose over the 4 years she had it). Again, this is very subjective and my own personal choice/tastes. Everybody's different.
