if the chasis was involved, FORGET ABOUT IT. No matter how good it is repaired, the car will never get back it's factory balance, the chassis will never hold the ground as it did originally... even with the most accurate tools, you can't restore initial status, so they tend to compensate with allignment and suspension, but the car will be dangerous, for it will tend to oversteer and understeer, and go off line when hard braking...

if the chasis is not envolved however, then go for it, it's a great deal...

my two cents on the subject...
