engine number can be re-stamped. so that is salvageable. ive done re-stamping before (B20 stamped as B16A). but still depending on the damage of it.
problem comes from chassis number. ive heard of people stamping chassis numbers before, but this can be dangerous and puspakom checks in the future may give problems and end up the car blacklisted and/or confiscated.
talk to ur mechanic about this.. take pix of the damage and bring to him... if he knows someone who can stamp engine and/or chassis, show him the pic so he can judge.
u should also talk to the police and perhaps JPJ to check wat can be done on the chassis number issue so that the car can legally be on the road again.
i think ur options are
1/ take the money from insurance and get a new car
2/ keep it as is, turn it into a track car
3/ keep the car, repair urself. restamp engine number. chassis number leave it alone and be sure to keep a copy of police report and recovery report (if any) along with pictures of damage, pic of the car at the police yard etc in the car at all times. so if u get stopped and they question, u have proof to show what happened. may not be able to sell the car ever though. and im not sure how legal this would be. its a risk u have to take.
4/ another risk...restamp engine and chassis (if u can find someone to stamp chassis). fix it up urself and drive the car. again... might not be able to ever sell the car. if u do this, keep documents mentioned above in the car as well.
5/ fix the car up and TRY to sell... though i have my doubts ull be able to
6/ tear the car down and sell the remaining parts off.. bodyparts, engine parts, interior parts etc.
7/ talk to JPJ and police as mentioned above
however, my advise to u is....
swap out nice parts for stock/ spoiled parts. u could probably take the engine and gearbox out and swap in spoiled parts in it too. and sell the good ones (new owner will have to restamp engine number)
then take the money from insurace and hand the car over.
i say this coz even if u manage to get the car back on the road legally or illegally... the risk of theft will always be extremely high. ull have to worry about the car being stolen again and all that. no peace of mind. hondas are waaaaaaaaayyy too hot.
no piece of mind is the main reason why i sold off my EG6 after 7 years of ownership.
yes, i will accept their offer, and take out all the nice thing and swap with the standard one. luckily I still keep all the standard parts. not willing to take the trouble fixing it myself and a possibility the car is not road legal
