All depends on what needs to be done. If the car is intact, with body panels already fitting, with just a few replacements and repairs to make, then I say repair. In retrospect, I should have bought a new chassis. Even with that admission, the repair process was very satisfying. I bought the car for the experience of restoration, not just for having a cool car to drive. It's really neat to replace crossmembers, etc., and get a good result. Pride in accomplishment is important to me. My regret is not the time and expense, but the uncertainty about the oondition of the frame rails that I didn't replace. Of course I cut back to what appeared to be good metal for the replacement outriggers, crossmembers, and the like, but those frame rails are for the most part invisible. Seems solid now, so we'll see.
