As long as the 'old banger' starts and moves reliably, keep it. At what point should we subsidise new EVs versus just running old cars We shouldn't. The extra carbon-emissions from running an old machine is miniscule compared to the enormous amount of carbon-emissions produced by making a completely new car. (Whether that new car is EV or ICE is pretty much irrelevant, here.) And of course, running an old car is several orders of magnitude cheaper that buying a new car, whether that new car is subsidised or not.
