I would like to buy this 2006 GT but would like to know what i would have to fix and what could possibly be broken in a worst scenario and a good scenario. i am new to these forums

 

Welcome to MF. I think we need more info instead of a picture of a dented fender with a spare tire on.

 

The drivers wheel is pointing straight and this one seems bent

 

You can not tell much from a picture, but best case scenario is the lower control arm is bent, the R/F bearings are bad (or should be changed), the R/F tie rod end and possible inner tie rod end, strut is bent. Worst case is all of the about and the frame where the lower control is bent needing straightening or replace (good time to put a tubular K-frame, rack and pinion could have internal damage and the R/F apron where the suspension is mount could be bent as well. Someone would have to do a damage assessment to figure it out. Compare from the left side of the car to the right side and look for stressed metal get a tape measure and take some measurements. Bottom line it could be as easy as a couple of hundred to a couple of thousands. I refer to my first statement, you cant tell without seeing the car in person.
I've been a mechanic for 38 years, and have repaired many font end crashes.

 

Sorry I didn't even address the obvious body damage in my description. It looks like a front fender is needed and some inner fender well parts on the right side. You can get most of that stuff from a wrecker for not to much, as you can get the other parts I mentioned as well. Could even be in the radiator support as well.
