I just purchased a 2010 DTS about a month ago. It had 17,550 miles when I bought it. Couldn't be more satisfied, "old school" conformable ride. I too looked at 2011 with more miles and for more money. I found the 2010 to be a little more comfortable. Lastly, the CarFax did report a minor accident to the right front. I had it checked out and also purchased a G.M. 4 year, 48K "bumper to bumper" warranty.
