I would fix it if it were mine.

When I rear ended a F150 on the highway, State Farm totaled my 2002 CTD 6 speed. I bought it back and later sold it to a guy that rebuilt it, I needed a new knee and my wife could not drive it even if I fixed it. The radiator was ruined and it needed a hood, bumper and both fenders, but the headlights were not broken and the air bags did not deploy! I actually made money on the sale and the new owner is very happy with it. If it had been an automatic, I would still have it.
