Its hard to be sure but it looks like its just body damage. Seems that your door took the worst of it which may work in your favor. Set it up on stands and go underneath for a look. The frame rail is about a foot apart from the rocker panel. Have a look at it and see if its bent. Try
www.car-part.com for used parts. I did see some doors for your tercel but couldn't get a specific listing since I don't have a zip code for your area. Your gonna need to do some hammering on the rocker panel and maybe the LF quarter panel to get the new doors to fit properly. Looks like part of your plastic fenderwell is sticking out. On the bright side, my sisters '02 Escort was damaged pretty badly in the same area. She managed to roll it off a small cliff (small being about a 10-15 ft drop) down into a creek bed

. After much hammering, a new windshield and pushing the roof back up, it still drives to this day. And by some miracle with no alignment problems.

Good luck.
