quick ? on 96 mustang gt

[GONZO99TA]

looking back over my previous post i forgot to mention the car has been in a wreck. that is the reason for the low ball offer. it got a new front bumber and roof skin. none of the original glass except for front windshield were damaged. airbags did not deploy. i'm not opposed to buying a car with a salvage title for the right price.
it would turn into a summer daily driver for my wife (she has a blazer for any bad weather) and possibly a future project for me to autocross on the weekends. kbb or nada are starting points, but neither will give value for this type of situation.
alot of members on here could rebuild a mustang in their sleep so mainly i was looking for opinions on what to watch for in this car. i would take it to a local body shop and have them check the underside for straightness of course. any other suggestions?
