Most rust on a coupe or any car can be fixed it just depends on how much you are willing to spend. The only really dangerous places is the front box chassy. And the main inner frame or Structure of the car
The value of the car dictates how much you would be willing to spend on rust repairs example you wouldn't spend 10 thou on a car that was worth 5thou unless it was a sentimental thing.
It is totally up to you how far you want to go!!!!!!!!!
Our cobra is a perfect example it had ALOT of rust see pics
The amount it cost to repair our cobra it should have been reshelled but for obvious reasons we didn't do that.
