This is my second Camry the first one 2007 V6 logged on 189K very strong performer until trans went out back in Aug 2010 that's when I took delivery of the 2011 2.5L auto which now as 45K.
There is little difference between the years, but for 2012 that should change new model make over.
No problems so far the engine along with the 6 speed transmission verses the older model using a small 2.4L and a 5 speed transmission makes the difference I think.
There are none. Its the same design as the 2007 model with only a few changes on the out side, but she does run and rides comfortable going down the highway.
