Roll cage

Moin Together, I intend to look at a vehicle which is equipped with a roll cage with cross truss of the company Wiechers Motorsport. However, since I do not want to use the vehicle for motor sports, but would like to mature slowly to the oldie, I would like to know if such a cage is to be removed without destruction. So whether something on the vehicle has to be “destroyed” or whether the cage is destroyed in this action. Furthermore, it would be interesting to know if such a part may then be used elsewhere, since I can then sell it as a used part, after all the parts are already damn expensive greeting Kester
