BMW of Barrington review

I can’t say enough about the outstanding service at BMW

September 4, 2025
By Cherin khanania from Elgin il

I can’t say enough about the outstanding service at BMW of Barrington, especially thanks to Justin in the service department. He always goes above and beyond to take care of us. Justin is professional, responsive, and truly committed to making sure everything is handled quickly and correctly. No matter the situation, I know I can count on him to provide updates, answer questions, and ensure the work is done right the first time. It’s rare to find someone so dedicated to their customers, and Justin has made every experience stress-free and enjoyable. Thank you, BMW of Barrington, and especially Justin, for always delivering such an exceptional level of care and service!

2019 Cadillac CT6 3.0L Twin Turbo Platinum review

Amazingly smooth, well-made

December 6, 2022
By Car lover from saint louis, Missouri
Owns this car

I'm trading my 2019 CT6 after two years. Have really enjoyed this car. There is no better highway cruising car ever, it's incredibly smooth but tightly built, not sloppy ever. Great gas mileage, very peppy, and beautiful. The electronics are very easy to understand. The only complaint- driver's seat too short, I'm 5'11", long legs, and I had a buy a bolster cushion. Otherwise, I've loved it. Trading up to a BMW 8 series for more excitement.
