Punjab website is far better than sindhs of the following reasons
1 It contains complete details of all the owners of a vehicle whereas sindh shows only last owner.
2 There is no mention of colour of vehicle in sindhs website whereas punjabs website has an information about the original colour of vehicle.
Although the computerised plates were first launched in karachi in the 80's but I am afraid to say that the sindh excise although being the first to introduce computerised registration is far behind its followers such as punjab and ICT
