It is everything I expected from Cadillac. Love the comfort and handling as well as the beautiful design. Gas mileage is great, average a little over 28 mpg on a recent 3,000 mi trip.

Ride is awful for a Caddy. Low profile tires is the culprit. hit a curb, no tire scrape just grinding of the very expensive wheel. It happened with my 2013 XTS and the CT6 with same type of low tire will cause the same problem in addition to causing a bumpy ride. The smoooth Caddy ride generated a lofty reputation. It is sad that it is being abandoned due to wrong tire height is being used.

When I bought this I expected transmission issues but there are a lot of hidden issues that the dealer should have been aware of and didn't address before they put the car up for sale. All four wheels are bent and need to be replaced because the car shakes very badly. I also think the shocks/struts are bad due to all the vibration. The sales manager did drive the car so he should have noticed it and had his shop look at the cause. The struts can cost up to $900 eack and the wheels from $300 to $500 on Ebay. I did request their mechanic drive the car and see what issues there would be because I had to fly in to see the car to buy it. I was hoping that the vibration was due to the tires needing to be balanced. This car does not cushion the road like the 2 others I had driven. My test drive was a bit short and not on a highway so most of these problems did not show up until my drive home. They did give my a limited warranty but at over 300 miles away I'm not sure how well that will work out. Worse case is I'll to drive it back and let them fix everything. That would cost around $500 for gas, tolls and an overnight stay at a hotel.

It is not the classic Cadillac. It is very sporty, high tech-which I love, but definitely Cadillac top of the line.

A/C not good

I like this car a lot, but in Texas the air conditioner just doesn't work. I have had it in the shop four times and they always tell me there's nothing wrong with the air conditioner......and then they say that I need to have the windows ceramic coated. Soooo, if it works correctly why would I need coating? If it sits outside while I am visiting my family, it takes about 30 minutes to cool down, and usually it never cools down enough especially for people in the backseat. I think I will go to Mercedes next as I never had a problem with that brand.
