I think it depends on how deep your pockets are, you see a lot of the P1 guys completely stripping the underside of the car, painting the underside, re-plating all the nuts and bolts, powder coating the arms, brackets, mounts, subframe etc and replacing all the bushes, I should think you're well into 4 figures by that point though.
Krissyb did a good thread on his car, all done on the drive on axle stands as well.
