I did a hybrid solution with both push/pulls and high torque RC servos. I ran the push/pulls to a location under the panel, where they are both out of the way, but in the event of a servo failure, I can reach them (barely).
The servos are powered by an RC BEC (basically a 12v to 6v transformer) and potentiometer knobs on the lower panel are wired to an Arduino that controls the position of the servo. It gives me very precise control of the servos. This is handy in the 10, because it's a very narrow margin between frosty toes, and feeling like your legs are ready to melt!
It also allowed me to put the heater control knob for the rear seat heat in reach of the rear passengers, on the back of the center console.
Here is what the servo bracket I made looks like. It's mounted on the bottom of the subpanel flange on the far right side:

That said, doing this did take a few iterations to get it working reliably, and I bet I have 30-40 hours invested in it. Push/pulls alone would have saved me 95% of that time and effort.
