Surprisingly easy, my mother demonstrates getting in and out of the progressive sports car with ease, it's far more than practical than you' give it credit for.
The swan doors are simplicity to operate and the fact the door opens upwards it's far easier to swing out.
My method of entering and exiting the vehicle is slide onto the i8 styled step, place foot between pedals and slide in whilst supporting yourslef with one hand on the edge of the roof.
Reverse this method when exiting the vehicle.
Overall rather simple, Michael's Grandad in his eighties can spring in and out with ease, watch out for our guide to getting in with mobility issues.
