CADI FAN!

I think this car this amazing! Everything cadi has always lived up to be! I can't wait to drive it! I owned a cts a few years ago and wasn't disappointed back then either. I haven't drove this one yet but I am so jacked! I'm the pickyest of picking out phones and cars. I will look forever before I finally pick one to take home. I am thrilled about driving this car and I know I won't regret it.

Cadillac St4 2020

I bought 2020 st4 with 5600 miles since I bought this car have problems with breaking & took it to the shops & they don’t know what is wrong and without doing anything to it send me home with the same problem. I contact Cadillac and they saying something in design like break pads to fix the break problem, but not out yet. We don’t know how much more time to wait for this problem. Lol

I love my CT4!

The CT4 is a real driver's kind of car. It has great style and great performance. Having the Premium Luxury model is nice. The leather seating and cold weather package along with many other luxury items makes you feel special.
