I do not like following items in new Altis Grande. Can anyone suggest their replacement from open market? Any online link shall be helpful.
2- Sun visors
3- Trunk / Fuel Lid Opener levers
Clock is fine. There's no substitute either, so get used to it.
Sun visors in the previous corolla could be swapped with Axio visors ( I have done it in my 2013 1.6 GLi ) but the latest corolla has a different fitting. You can remove one and take it to any used parts market and ask them if a similar good quality japanese one is available that fits.
Similarly the boot/ fuel lid hinges can be changed with those of Premio. But you will have to look around quite a lot for it.
