Hi Tom, the Mercedes CLA shooting brake premium plus is automatic and has leather fully adjustable electric memory seats, including lumbar and angle of seat cushion. A really good feature are the kinetic seats which continuously makes minute adjustments to the seating position for the driver and passenger to reduce strain on muscles and aims to improve the health of your back during a long trip. This feature is now a must-have for me ( I have nerve damage to my right leg and have had spinal cord surgery after a hit and run accident) I also find it a lot easier having the controls on the door rather than on the seat.
I hope you find a car that suits your needs.
