There's a never-ending argument going on regarding the proper way to maintain a vintage car. One side insists that collector cars should be kept in "as is" condition, assuming the car is relatively clean and drivable.

Another prefers that the vehicle be stripped and rebuilt from the frame up, then displayed in better-than-new condition.

A third group would rather add modern engines and running gear while keeping the body and interior more-or-less intact.

So who's right?
