Electrifying old cars can make a ton of sense, but it can also completely miss the point. Especially when you start talking about cars that originally sold with crappy automatic transmissions, like a lot of Toyota MR2s, or an NSX, or any car where the engine was a real maintenance nightmare and not worthwhile, or where the transmission was a big problem, could be excellent candidates. Basically cars where engine/transmission swaps seem like a good move.
E46 M3 SMG
I think a transmission swap is more worthwhile in the case of the E46 M3 purely because the S54 is a gem of a motor. I think the perfect candidate would be something like an XJS V12. Beautiful car with a big lazy engine that doesn't tolerate neglect at all. An electric powertrain is perfect for the character of an XJS.
