@emenent you mean you lost your car and now lost 300k too??? I can understand your feelings. When we lost our car, someone advised us not to spend a single penny on any efforts to recover the car. Agar milni howee to mil jaye gi else but its better to write it off and move on. that simply lessens the pain although not the loss itself.
A lot of people offered us their services to get us a non custom car with tempered chassis thru soopardari but we resisted the temptation. Actually it was my Dad who simply refused to go for any illegal solution.
Someone deputed at Adiala jail got with some car thieves inside the jail and asked them to locate our car. Thru cell phones, they figured, our car never went across Indus river and hence it was concluded that the car is within punjab, stolen perhaps by immature/non pro thieves and most probably knocked down in pieces within a day or two after the theft. Don't know if that was correct information at all but we never found the car during last 9 years. Thought to share with you and hope it might offer some help.
May Allah give you courage to bear your loss.
