honestly in the grand scheme of things this will make hardly any difference. If you can afford a 100D then your time is clearly your money. With the 100D you might now able to cover distances you couldn't before (i.e. for long commute) without supercharging and you can also supercharge more miles faster. Which means you have more time for a leisure activity of your choice. Even if you drive 50000km a year with superchargers, which is highly unlikely, you are only forking out about 1000-2000 dollars out with that. Really not much considering how much you payed for the car.
