I am still regularly riding my 750 BMW that I bought new 42 years ago. Over its lifetime it has taken me to work regularly and on long distance europe trips. I have carried out various repairs but it still starts first time and I can still get spares for it ( although at rather exorbitant prices!)
I recently visited the Triumph factory at Hinkley, great day out and very interesting . Very tempted by a new bike but will it still be going in 40 years time i'm not sure? will I be able to get spares , I suspect not, can I service and repair it myself absolutely not !!
Exactly the same applies to my 26 year old Peugot based motorhome in comparison with a new one,
Companies profits and shareholders dividends are based on selling us a new item just as often as they possibly can and marketing is based on convincing us that things we might only actually want are things we desperately need.
Like NDIY all my machines are over 40 years old and still perfectly fine.
