My preferred driving position has always been more reclined than most. Mainly do to my odd shape - short legs, long body. Our day cars have to have memory seats as our driving positions are so different. Nearly every car I've had in the lat 40 years has had reclining seats and I've had well over 100 cars!
I've managed to adapt the Morgan seats to give something like a decent position but recliners would definitely be a better and more comfortable solution. I find I get a lot of neck and shoulder ache after driving for more than a couple of hours.I'm not desperate but would like to find a better solution.
