roadside fuel is forbidden in any car. try to fuel up all your cars from reputed company-operated petrol stations otherwise, any car would ruin due to low quality mixed petrol.
you are taking a wise decision of opting for 580 pro as BRv is not suitable and comfortable at all. In the case of 580 pro, you would have full 3 years of peace of mind as your vehicle would be under warranty.
just buy that car and enjoy.
don't think too much otherwise you will end up buying nothing.
