2015 vs. 2016 vs. 2017 what's the best year to buy
 

What are the differences between 15MY, 16MY and 17MY CTS models. I have heard about you want the Aisin transmission and try to stay away from the 8L45 transmission.

I have a 16 and love it. I also have had a 10 and an ats 13 but this cts 2016 is by far my favorite of all. Only issue with it is the pano make a bit of noise sometimes when pulling into a drive way.
