Premio is not Officially launched in Pakistan hence unavailability of Genuine glass from Toyota . If any 3s dealer is providing then it's probably 1st copy and they aren't even answerable for that to Indus since they are not allowed to cater to JDMs .
Only for for OEM which is widely available in Pakistan for eg Fuyao . Never go for aftermarkets in windshields they are the main component of your car worth more than a bumper hood door or any other part since you will be looking through it 24 hours and non availability of airbags in most cars means it's the major life saving part.
