I started shopping for 2009-2012 California recently. Trying to stay around $90k all in so probably won't be looking at more expensive 2013-2014 Cali 30 models. I know 2012 got an additional cooler that helps with heat related failures. I don't know if all 2012 had the cooler or if it was a mid-model-year update. If you were shopping early Calis, would you be extra concerned with 2009-2011 versus 2012+? Is it worth it to only look at 2012+?
