judging by the black rocker moulding and side stripe, i would say it is a V6. looks like they drove it a little harder than they could handle too bad.... on the plus side, there are a few more used parts in the junkyard now....if anything is usable.
looks like a hole I had in my honda accord back in 95. Road came to a T and dropped down a hill on the other side, lots of trees. I didn't get to stop and went off at about 35MPH, hit a tree on the front drivers side and went down the hill spinning sideways. There was a hole in the roof of the car that looked like that. Didn't go through all the way, but it did go through the outer paneling. Probably a tree.
