Hard to say until we see some pics, but it doesn't sound that bad to me. A lot of spec guys break those suspension parts racing without any real ill effect to the chassis. This guy rolled his 3-5 times doing 75-100mph and he's bringing his back from the dead. So anything is possible. Of course it wouldn't make much financial sense to spend too much on a car that's only worth $12k on a good day. My advice would be to start calling around your local wrecking yards to get prices for parts you might need.
