I just traded my 2012 Tuxedo Black Titanium in for a 2014 Tuxedo black ST1.
And I am not looking back at all. the ST is WAAAYYY more fun to drive. I was looking to dump a lot of money into my titanium to make it faster and what not, and realized it was more cost effective to trade it in for an ST then it was to dump a bunch of money into it and be disappointed I didn't get the gains I wanted.
