Although there are some decent companies doing decent conversions out there you have to ask what’s the point. I love an old 911 as much as the next guy, but not sure i’d enjoy a converted electric 911. Part of the 911 experience is the engine, its short comings in power delivery, the vibration, the noise, the smell. Also stick a big heavy electric motor and battery pack in there and you completely change the weight distribution and dynamics of the car…another flawed, but endearing quality of such a car. So for me it sort of defeats the object of the point of the car in the first place. I’d much rather just have a modern electric car. The days of cars that are as much of an experience as a practical tool are over. The future of cars is boring, efficient, practically tools…white goods not for fun or enjoyment. So all the more reason, if you have an old classic car, to retain the originality and enjoy it for all its flaws. A bit like vinyl lovers.
