Hi, I have been lurking on the forum for quite a while. I am considering a CX5 and here in Florida there are still 17's to be had. (There are Grand Selects mixed in with a few Tourings and quite a few GT's.) The dealers seem to have a lot of 17 Grand Selects that are Certified with 6K to 10K miles on them. From what I read, they lack some of the electronic features but are otherwise similar to GT's. So, please help me understand why so many have been traded in so soon after purchasing. Thanks, Super90.
