I agree with "Image".

I purchased a high performance EV with a reasonable range to replace a noisy, not very refined high performance ICE car, not to save the planet.
I purchased the PV panels in 2011 to get the FIT payment and cheaper electricity, not to save the planet.
Both are economic decisions, made by the head, not the heart...

The Tesla M3 ER AWD is about 150kg heavier than the C63, has about 450bhp (published figures differ) and a better 0 to 60 time, probably it can get the power down in a way the C63 cannot.
The range is about the same, 300miles in the real world.

Filling up the Tesla at a Supercharger costs about £24.00, less if charging at home from PV free power, filling up the C63 costs about £85.00.
The Tesla Service costs are, as far as I can work out, about £250 a year, the C63 is twice that.
Road tax is lower, insurance is lower...

I rest my case

For a local runabout I'd get a Mazda 2, because it is cute, drives well and uses little fuel.
