2013 Cadillac CTS Gets Needed Attention Part 1: Oil Change & Transmission Servicing 

I bought a 2013 CTS4 Performance coupe in May. It had 90K and was super clean with all service records. Like yours it is VERY clean inside and out. I have done the oil change in both diffs and the transfer case. (really helps!) I have yet to do the trans and I hear on a AWD it's a little tougher. LOVE these coupes....mine is white with black int. Thanks

I'm suprised you didn't get a cts-v.
