Perhaps, like buying a car, you can just charge a base price (the Software alone) and anything else is an "add-on option" with appropriate prices.
maybe offer package deals of certain configs for like a few dollars cheaper than if you picked and chose.
i dont know what things will be offered hardware wise by QCar, but this seems a nice way to get it into the hands of those who want it, and without a lot of fluff. or, it they wanted, alot of fluff.
