who says foreign corollas are solid? I see them everyday - work on them too, their dashboard plastic warps, cracks and fades from heat, the wiring looming is useless, the fake chrome on parts is useless and either corrodes or peels away - the body skin is flimsy and squeaks and their floors rot out from salt.
Whoever buys a corolla already knows that such are all built in qualities of it.
If you are really sad about it then write a letter to toyota and complain on your concern of declining quality, you might get new badges from them. (I doubt that because corolla is not a flagship car for toyota anyway)
btw - I have seen this issue in Pakistan it was usually attributed to "sarviss teyshun" car wash using well water and dishwash soap to wash the car. Sometimes it was just plain and simple salty air corrossion.
lol - I work for Indus? - I dont even live in Pakistan.
