I have a single working throttle actuator for sale with a 2011 build date that was installed on my 08' in 2011/03/21. I have documentation showing this replacement was done at 35k miles so the actuator has 20k miles on it as my car is at 55k miles when I removed it last week.
I can supply this paper work to any interested parties. It is located in Calgary, Alberta, Canada and I am willing to ship at the buyers cost.
