Don't forget, the saddle issue - most of us ride saddles that cost, what £30 at least up to £60/£70 - that's way more than these cheap imitation saddles...that are on most bikes.... ride those saddles and you will have trouble.
Even my Flite Titanium (original pre hole type split you in half type) is still comfy - although you need to harden your ass...but I suppose over 12 years with it should be OK..... had two kids in that time, and the bits are still working...
