David helped me get into a vehicle when no one else
David helped me get into a vehicle when no one else could! I came from Elgin to the number 1 Nissan dealer in Illinois and they are number 1 for a GREAT reason! I love my new Sentra and it was because of David! Ask for him when you come and you won't be disappointed!
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Andrew Doyle at this dealership was amazing to work with.
Andrew Doyle at this dealership was amazing to work with. He was soft spoken, detailed yet concise. He was influential in making a deposit for a purchase. I had to pull out later for other reasons. But I give high regards to Andrew’s work.
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

I can’t say enough about the outstanding service at BMW
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!
Best truck I’ve bought
The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.

Perfect Vehicle, great salesperson!
My sales person Alex Valdez was great! I thought he would give up on me because I was very picky and expected alot. I had resigned myself to keeping my current car, but then he found me the perfect vehicle and I love it! All in all it was a pleasant experience and I highly recommend McGrath Honda/Elgin. Just ask for Alex Valdez and he will work hard to find you what you want!

We bought our new Acadia from Mike Rancharran at Gurnee
We bought our new Acadia from Mike Rancharran at Gurnee GMC, if you are looking to buy a car ask for Mike, he will do what he needs to do to get you a great car at a great price. What’s nice about the dealership is you deal with one person not 3 or 4, they are not pushy and if they don’t have what you are looking for they try to find the car you want. Thanks Mike !!
