3RD CAR PURCHASE!
3RD CAR PURCHASE!! This is the 3rd vehicle we purchase at this dealership. The cars are amazing and the prices are great!!! The service is amazing. They work side by side with finance company making everything run so smooth and easy. The staff is always super friendly. The inventory does not disappoint. So many great options to choose from. Recommend 110%!!! Would not buy a car anywhere else!!! Thanks CAC!
Love at first drive
I love my 2020 x3m. I will own this until the wheels fall off and replace it with another x3m. The gas mileage at 19.5 miles a gallon is the only bummer but it’s well worth it.

Great SUV
Talked on the phone, and the second I walked in, very laid back and honest people, best car buying experience I’ve had, Ryan and the whole crew in there are amazing!
Awesome!!!
I’ve owned a 2020 x3m competition since the month they were released. First let me knock out rough ride thing. If you ride on the stock Conti summer tires all the time, yes it can be rough. I switched to to Michelin all weather after 11,000 miles and it made a huge difference! A much better more comfortable ride Side note: when I would swap Conti to winter tires also a huge difference! The stock summer tires that come on the car are incredible for handling on a track which the car was made for but, the car feels much better with Michelin all sports all seasons. This car makes me happy every time I drive it ! So much fun to drive!

I recently purchased A 2018 Alpina B7 from Ray at Motor
I recently purchased A 2018 Alpina B7 from Ray at Motor Cars Of Chicago. When I purchased the car I made it clear to Ray that I was going to be in need of the title in ASAP fashion – Ray said I’d have the title within two weeks and boy did I just like he said he fulfilled the promise he made no questions asked. Also on the way home after taking delivery, I had a very minor problem that turned out to be a bad battery. Ray was unaware of when we took delivery of the car – Ray didn’t hesitate he reimbursed me for the batteries I had to have installed at the BMW dealer by the BMW dealer. He said the car was flawless and he stood behind that statement. Ray is very straightforward and no xx perhaps not full of warm fuzzies for everyone but a great way to do business, especially in the luxury and highline car business. I find Ray to be honorable direct and stand up and we’ll do business with him again if I had any reservations about doing business with them before this transaction, they are all completely gone and yours should be too. Thank you, Ray for a great transaction and a great automobile.
Sedan vs SUV
Absolutely love this SUV. Had a M340i and it was quick, but this X3 M Competition is wicked. Love the quickness and the firm ride. Glad I made the switch. Lots of talk about the firmness and the rigid handling, but try one and see for yourself.

A fun and enjoyable ride!
Yes, it’s crazy powerful but you can definitely tame it to be a fully enjoyable ride for everyday use. I look forward to many years with my new X3M!
There are 3 matching cars close to your year range.
