looking forwards, you can take it to good alignment shop to let them check the undercarriage or car and check if measurements are out of range or not.
if the wheels alignments and other measurements are accordingly to spec , then u have a car which is driving nicely and not jumping around ont the road.
if something found which is not normal, you can ask them about ways to fix that. Mehran is pretty simple car and most of things can be fixed easily without spending a fortune.
Next step is to let a good experienced bidy shop guy to check the body penals and other areas. let him find any issue and ask how fix it.
i think this will help u make a plan to get the car in reasonable shape.
remaining things are mechanical and electrical issue, related to engine and suspension etc.
such issues can happen to any car be it accidented or not, so i think its not related in this discussion.
