Congratulations to all the new owners and I hope these cars serve you well.A few words of wisdom (I would like to think of it as wisdom as least).
1, HID's in reflector housings are a nightmare for oncoming traffic, please do not do that.
2, Speed limits are there for a reason, I would be really interested in knowing safety ratings for a PKDM corolla (they might not be similar to Euro or USDM corollas) but I am sure it would not be very reassuring.
3, Aftermarket products are nice but in my personal opinion (and because a Corolla is considered as an upmarket, nearly aspirational vehicle in Pakistan) they ruin the look of a car.
Just my two cents of contribution, happy and safe driving.
