My situation was a bit different as my car was totaled in a garage fire. I had my car towed to the tow company's impound lot and the next day retrieved it and brought it to my shop as I didn't want the insurance company to take possession and would not release the title to them. Two inspectors came by and appraised the car and I got what I thought was a fair offer after turning down the first one. I bought my car back for $1000. I can't believe the gas tank didn't rupture and the rear window blown out! Definitely get checked out as you WILL have issues from that bad a hit...
