I'd love to put in an order for the new c63 but I've just been out in my c63 for the first time in a few weeks and it struck me why should I shell out an extra £30,000 or so to buy the new version (apart from keeping up with new technology) when my car is so quick, way beyond sensible speeds on public roads, we get so persuaded by advertising and journalists reports, I've been down this road many times before, 911, Ferrari, Lamborghini, I'm coming to the conclusion that if I want to move forward in motoring terms my next car will be a Tesla.
