Then, you can also buy relevant items from authentic and authorized shops in Lahore. There will definitely be reputed and respected shops in Lahore, irrespective 1s or non 1s, which sell Toyota genuine parts, at reasonable prices.
Lastly, you can have the relevant parts replaced from either any authorised Toyota dealership (if warranty issues are there. But if warranty issues are there, then you are also bound to buy parts from them only too) or any good garage.
I hope, it helps and guides. Thank you.
