Having sat in two now myself and having watched many get in / out at Goodwood BHM day, there are many physical specimens who will find it very hard to get either in or out without using the seats as a step. This isn't a problem as such! But you may be disappointed if a passenger marks your bright yellow leather seats with muddy trainers...
Many people have trouble getting into (don't know how too ) my 4/4 and scuff up the carpet in the footwells .
Entering the M3W would be very similar to entering/leaving a Caterham/Westfield/...... and I have never seen anyone who does not stand on the seat.
