One of my earliest cars was a Citroen DS - a car with a FEARSOME reputation for what some might call needless complexity,
I believe the DS actually came in two flavours, the bells and whistle one and one that looked the same but was rather more basic under the skin. I dont know what the relative fates of the diferent variants was though.
Pretty cars though!

Citroen's (very game!) attempt at an automated manual transmission with a dry-plate clutch (which manufacturers are only just starting to sell in significant numbers today)
Basically, I am not opposed to new technology, I am opposed to the ABUSE of new technology.
Item. Toyota yaris with auto-clutch manual gearbox varient. (since you mention it)
Clutch actuator failure. There are two possible faults. The "Sphere" (like on a citroen) or the controll unit.
The only way you can test the sphere is by substitution (when I last looked this was £400 flaming quid, though that was a couple of years ago)
If that doent fix it, you have to replace the controll unit. Now, though the sphere is available without the controll unit, the controll unit is NOT available without the sphere

another £800!!
So one has to advise customer that "worst case scenario" is likly to be £1200 (or near enough) which includes an unwanted pressure sphere (which cannot be returned for credit because it was special order/been used)
All to replace a £10 cable!
Now, I have no objection to having an auto-clutch in principle. Wht I object to is the way the manufacturers seem to use this technology to control the life cycle of the vehicle. I am sure, that on average, these systems might last 10-15 year without issue. But failure will almost certainly scrap any yarris over 8 years old! even if there is nothing else wrong with it!
Another example. Nice little Nissan Almira, perfect condition but ABS light on. New NSF wheel sensor bneeded. Now this is JUST an simple inductive sensor, nothing complex. Yet Nisan want £400 flaming quid for it! This is clearly "priced to encourage scrapping" on any older vehicle. (It actually has a Bosch part no on it but the number is not available for general release. Vauxhaul do the same thing with their small diesel engines. AE could make new psitons for then for £50 (or less) but vauxhal wont release the design and thus hold the price at nearer £400 each! Now, why do you thingk they would want to do that?)
Now, what really rankles is that I doubt if the "factory gate" cost of the Toyota assembly is more than £50, (if that) The Nissan wheel sensor probabally no more than 50P!
Why do the manufacturers charge so much then??
A) because they can
b) because it suits there business model to have a range of system critical spares priced such that they will never actually be used on any car more than 10 years old in order to ensure a continued demand for new product.
The built in obsilessance isnt so much about building stuff to fail. Its about making it too expensive to fix when it does! Remember, back in the 70's people would carry on with mechanical repairs (up to and including exchange engines) as long as there was a body shell left to bolt it onto because it wasnt particularly expensive to do so. They would only be scrapped when it was physically not possible to carry on repairing them!
This is what I am objecting too. The (undoubted) improvements in build quality and materials shuld be yeilding vehicles that last almost indefinatly, yet they only (on average) last two years or so longer than back in the late seventies when they fell to bits after 12 years
Now, I accept that if the ease and low cost of repair of 70's cars was combined with 2008 build quality then the industry would have big problems since ther would be almost no demand for new cars. (since once everybody who wanted one had one, you would only be needing to replace write offs as a result of accidents.)
This would undobtedly be "Interesting" Our current economic models (And indeed, political ones too) would have great difficulty coping with a "Durable" socioty. But perhaps with the dwindeling availability of high grade mineral resourses (Everybody bangs on about energy, but energy isnt really the big problem) a shift over to a more durable socioty is needed, we need economists to think about how an economy would function where nothing ever wears out and/or is indefinatly repairable .
