Hyundai Santro Problem (Doors/Windows)

[adyiator]

Please help...I have this 2001 Santro
My door opener and window opening (manual/crank) wear out every 6 months,
and the new parts available are not also durable.
Do you know how can I get these parts for my car which last longer than 6 months ?
Hyundai may not have build good quality parts but surely someone else would have found a solution and developed good parts ...
Any idea how and from where can I get good parts ?
