So now you have two host computer options, the Win7 Netbook and the Win10 laptop. I'd not cart a laptop around the car if it also was needed for other things as dropping it on the garage floor might limit your future use of it, so the more disposable of the two would seem the best bet. The only other thing you might need is an in-car plug in charger to avoid over depending on its battery when using the machine in the car.
