G'day and WB. If you are looking at an 06 then ask if it had the update kit put in. It may not ever need it, but then again. . . The main symptom of it needing the kit is that it jumps out of 2nd gear at WOT. Sometimes the problem doesn't surface for as much as 20,000 miles. Problems were sorted by 2008(ish) so a 2009 model, or later, should be solid.
