considering purchasing this car. How much needs to be replaced on the front end. Really appreciate it.

 

Pics are with hood closed/latched

 

Upper rad support is pushed back, it should be parallel to the radiator, not bowed in.
Hood is bowed up from being pushed back, if you are patient you might be able to massage it back down, it won't be pretty(already has a kink in it), but it will work.
My main concern is what does the crash beam and bumper support brackets look like underneath the bumper cover. If those are pushed in/damaged they will also need to be replaced.
If the airbags are not deployed then the car can be fixed fairly easily.
