How much is to much??

Does the car have some sort of symbolic meaning to you? If so yes.

I'm replacing my front aprons, front crossmember, radiator support, floor boards, some of the trunk area. I don't think it's too much, because I had the choice of cutting my losses and finding another vehicle and swapping my drivetrain into that car, but I saw it as a hassle and the potentional of having something else wrong with that car, I'd see myself back to ground zero. I'd rather fix it the first time.
