Good day, cars with internal combustion engines are harmful to the environment, generate loud driving noise and may not be operated in some big cities any more in the near future. I am looking here for the opinion of experienced oldtimer experts. How about having older vehicles rebuilt to an electric car? How expensive should such a conversion be? How high should the power of the engines be and how far should one be able to drive with a battery charge I am aware that in a way the cars lose their charm. The sound of the engine, the screwing of the old treasures, it is quite part of a classic car. But in my opinion it would be even worse if you were not allowed to operate these cars in big cities. I am looking forward to numerous answers and opinions.
