We've had a few cadillacs in the family over the years. I've had good luck with them. My favorite was our white 1991 Sixty Special. It rode like a real Cadillac. Now they all ride like a Mustang GT. Even the DTS rides a bit rough.
Sold the Sixty Special after we bought a 07 CTS a few years ago with 51k on it. It just rolled over 100k and have had zero issues other than the CD player had stopped working, then fixed itself when i replaced the battery a few months ago.
About two weeks after i sold the Sixty Special to a friend, his wife opened the door into the path of a city bus. Such a shame. Destroyed the car. They only made less than 800 of them that year. I picked it up cheap because it needed a water pump at the time. It had over 200k on it when i sold it and it was still running strong.
I got the 2008 STS cheap at auction about two years ago for our daughter and never had time to address some of the nick-knack issues. It has the 4.6 northstar. 320hp/315ftlb. Runs like a rocket. Other than a leaky right valve cover gasket and a fried cat, i can't complain. 126k on it now. I don't really care for the color, but whatever. I just need to get things working and get it sold.
She had been saving her money and just bought herself a 2013 SRX with the direct injection 3.6L. I don't know much about the 3.6 but i guess we'll see how it holds up. It's got 120k on it but is dry as a bone underneath. Picked it up cheap because of the high mileage and the CUE touch screen is dead, but voice command and steering wheel function still works so no biggy, but she ordered a new screen for it anyway. So i'll have fun replacing it. $400 screen coming from china. I hope it lasts longer than the original. They've had issues with them since day one. I guess the sun cooks them.
All cars have issues sooner or later, but i'd take a caddy over any eurotrash car every day of the week.
