They also will likely do something with how they offer options to make it not clear. From 2007 - 2008, the SLE base price actually went down by a couple hundred. Of course, in 2007, the SLE came standard with captains chairs and in 2008 it came standard with the bench. So it can be tricky to figure out what the real change is.
In my experience though, unless you plan on keeping the car for a LONG time, it is better to pay the extra for the newer one if they are not offering some type of huge rebates on the older ones.
