At to what point is a car unfixable?

[koukizhang]

Just wondering at what point is the frame of a car past the point of no return? My friend just got in an accident in his S14 and was devastated. Instead of losing hope, he's going to tube the front and rear and repair all the areas that were damaged.

This got me thinking, at what point can a car no longer be fixed? Specifically, if the frame got damaged, is there a way to pull it/repair it? For example if you were t-boned in an accident and the frame rails were pushed in, is there a way to come back from that?

Just wanna know so I can stay positive if my S14 was ever wrecked...
