Used 2009 - $64k
New 2010 - $67k MSRP = $61.xk invoice
The extra options on the used is ~$5k. Assume you add the same same options to the 2010 it'll cost you ~66k invoice. I don't see any reason to get that used car!
The 2011s are around the corner, but they aren't in the lot yet. From what I read people are still getting the 2010s above invoice. If you want a deal on the 2010s, wait until after the 2011s are in the lot.
