Sorry to hear about the accident. I think the chassis probably lari due to the accident. The rocker panel is stuffed, therefore making one side of the car shorter than the other, thus making the car wanders (to the co-driverside) when driven.
Chassis pulling won't be cheap. I sent my car (worth 10k at that time) to a chassis alligment workshop in Shah Alam last time (the biz now is closed). They checked the aligment and quoted me 2k. I sold off the car instead. I was just not worth the job and money. Also, the ppl said that even after the chassis allignment, it wont bring the chassis back to true.
It's sad that you treat the foreman as fren, and gave him business....but the foreman treated you as a fool and treated your car worst, like some sort of stunt car. Is that what a fren does???
Since the foreman gave you such lousy treatment, I say you SUE him until his pants drop. This irresposible ppl cannot be left free in the society. Put him behind bars, or sue kaw-kaw him until his biz tutup kedai.
Remember, put a stop to this stupid foreman. if not, he would probably drive again like this in other customers' car.....doing more damages, and perhaps endangering other road users.
Keep us posted
