My dream with a car like this is to never open the doors -- hell, as far as I care the door is broken. You've got to hop over the door and land perfectly in the seat.
Reminds me of the first day I bought Fiona and we drove around the neighborhood, parked and then I could not put her in reverse did not realize I had to push stick down then back
I've always used the standard, left hand, back hand method. It has alway been awkward. I have a set of coupe handles that are black plastic with a longer reach and a big flat on the end. I'm thinking of trying those to see if they are easier.
