I agree with a lot of your points including the seats, 1SS vs 2SS and difference in stiffness for MRC. However I'm not sure you're driving a stick shift right "I picked A10 so I don't have to jerk off that stick in stop and go traffic" lol. There is a mod here on the forums where you can make the seats recline more but I'm not sure it's worth the trouble. I would only need to recline the seats back that far if I was taking a nap in the car.
Enjoy the car! but not too much
