I wonder if things can last longer - it is just people don't want them to and there aren't many tradesman that have the right skills because manufacturers encourage the 'replace not repair' culture. This has done well, moved three times but has had three sets of bushes, two door hinges and a couple of other things that I can't remember. I found a repair guy that was good value for money and I even replaced the door hinge myself last time it went without too much trouble. It probably should have been replaced a lot sooner due to water efficiency etc and maybe it has finally reached the end.
