So here's my situation, and I'm trying to figure out what to do. The lease is up on my current car, and I'm thinking of buying a Volt until my M3 comes. I currently don't have a garage, and the closest my car can get to an outlet is about 24 feet. Any outlet will be outside, under a bit of a porch. My house was built in 1930, so I'm obviously looking at $$$ for wiring upgrade. What can I install to charge the Volt now, and the Tesla later? Just trying to reduce the need for more electrial work down the road. Electrical jargon is all Greek to me.
