Read that whole thread -excellent one. I settled on the 2009, get all excited looked for flights to go and pick it up, but I now think it sold -even though I thought I had "reserved it", still waiting on a response from dealer so not looking good.
The 2012 has 85k and I spoke with the sales guy (who has been excellent) even sent him the TSB which he passed onto to service he said they only do that work if they here the "ticking" noise, so that would be a timing chain gamble. Their quote from 5-8k to do that work.
I think I am scared off of the 2010 later models, unless I buy one with a warranty, similar to the someone who posted on the forums about buying one thru Carmax.
Then I also spoke to our recommended Bay area independent shop "Roverland" and they said they do not do timing chain replacement -since they have seen people have them done spent 5-8k and still had issues after all that work. They said for sure the 2009 has a more reliable engine.
I will update as I have news. Loving this forums excellent source of info.
