When you book the car, what delivery date you got ?
The amount which you will pay to Lawyer, perhaps the same amount you can pay extra at showroom to lift a prompt availability.
This case will not be so strong. Eventually it will be you who have to suffer more. Honda is multi-billion company in PK and rarely your action will be noticed.
How can I say this? because I have been through some legal proceedings in last few years and at the end, nothing happens and we have to end up in compromises. PK courts are so busy. They will give you next date, then next date and then another next date and so on. After 1~2 years, court will order Honda to give you car with fine of Rs. 10,000/- for late delivery. Its not Europe my dear.
But even then I appreciate your courage. At-least someone will raise the voice against such inconvenience.
