Welcome to Morgan ownership and enjoyment of your new car. Not so many years ago an auto trans option would be unthought of in a Morgan, now though many UK owners opt for such on their Plus Four which uses a variant of the B48 engine offering 50Nm more torque over manual and of course the 8 speed is very slick and with paddle control. Note also for the Plus Six that's the only transmission option.
I also occasionally (but increasingly often) wear hearing aids. Its not unusual to forget they are in when jumping back in the car after a lunch outing. My greater concern though is loosing them.
