I don't know about this vehicle but as far as bonnet alignment is concerned, I think accident is not the only reason for misalignment.
I have 2000 model Suzuki Khyber and a few days ago I noticed that its bonnet is getting misaligned. I mean the distance between the fenders and bonnet on both sides is not uniform. My car has never been in any kind of accident, specially from the front. I don't know the reason for this alignment issue, I think its due to the thick rubbers I installed from a pathan.
