This is the fourth vehicle that we've purchased from ELCO
This is the fourth vehicle that we've purchased from ELCO Chevrolet, and there is a reason that I returned for my third Tahoe: they're the very best. Three weeks ago, I lost my husband unexpectedly and with two ELCO Chevy's, one 10 yr old Tahoe and a two-year-old Trailblazer that my children didn't want I felt it best to combine the trade-ins and purchase a new Tahoe that will take me another 10 years, providing me not only transportation but the security I need moving forward. The staff at ELCO were respectful, kind, understanding, and efficient. The purchasing experience was excellent from start to finish, and they took every step to make me feel like I was the only person in the dealership those two days. I am very grateful to Mark Gerecke and Branden Nehls for all they did to make the process as easy and comforting as possible given the circumstances. I am an ELCO customer for life.
Buy one if you can afford it
Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

I bought this after going to the dealer just to look at
I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Chase Winters was wonderful to work with.
We recently purchased a 2014 Mazda 3 from Lou Fusz Mazda on Lindberg. My husband and I visited every Mazda dealership in the Saint Charles/Saint Louis area. Our salesperson, Chase Winters, was very knowledgeable about the Mazda 3 and was a pleasure to work with. He lets you make up your mind with no pressure to buy. Chase stayed late after the dealership was closed to make sure all the paperwork was completed and the car was cleaned and ready for us. Everyone we dealt with at the dealership was friendly and helpful. We will come back to Lou Fusz and Chase Winters the next time we are in the market for a car.
Favorite car I have owned, to date!
The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

Purchased a new 2021 Premium Atlas
We live on the Illinois side and this was the third vehicle that we have purchased from Bommarito VW. My wife just loves VWs. The pricing and the inventory are just better as well as their Service Dept is just top notch in our opinion. Andre Branch is who we worked with on our last two purchases, which includes our most recent purchase of a 2021 Premium Atlas. Andre is a great guy with an awesome personality. He is not pushy, he is very professional and courteous. Andre just wants to make sure that you have a good experience and help you get what you want. His care for you doesn't just end at the door with the sale, he continues to follow up with you afterwards to make sure that things are going well. We will ask for Andre every time we need to conduct business at BVW. This last experience was our best one yet! Thanks Andre, keep up the Great work! See you next time....
I have enjoyed my vehicle.

My sales rep was JB he is the bomb diggity. Just moved to town they made my buying so successful. I'm very happy with the service that I received. I recommend anyone to purchase a car from Jim Butler finance operator Miss Mary she's great.
2020 Yukon SLE. Highly recommend!
I previously wrote a review back in 2021 While I was leasing this vehicle. Which still shows up. I just wanted to give an update. I ended up purchasing it after the lease ended. So glad I did. I absolutely love this vehicle. Everything about it. Minus the high back end and price of gas but you're gonna get that with V8 engine. Have had since the spring of 2020. Haven't had any issues at all. Still would highly recommend. Comfort, look, safety, practical, A+ Best vehicle I have ever bought. I would normally have been in a new vehicle by now, I use to upgrade every couple years but not after this purchase, Still very 😊 happy

Not super high pressure sales process
Had car salesman Hunter that was extremely helpful in finding a used SUV for my price range. Showed huge variety and among a variety of brands and even let us drive home to see if it'd fit in garage no problem. Price was acceptable and car we got was great! Highly recommend Hunter as salesman as he was more than accommodating to get the car we wanted.
Great truck to own.
Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

My experience at Frank Leta Honda was truly top tier from
My experience at Frank Leta Honda was truly top tier from start to finish. From the moment I walked in, I was greeted warmly, and it was immediately clear how much pride they take in their dealership. The space was spotless and thoughtfully set up to create a great customer experience. My sales associate, Cody, was exceptional. He was easy to talk to, incredibly patient, and thorough in answering all of my questions. One thing that really stood out was the way he took the time to visually explain the difference between buying and leasing…something that can feel overwhelming. He broke it down in a way that actually made sense, and I never once felt pressured. Instead, it genuinely felt like he had my best interests in mind. There was none of the typical sales pitch energy that can make car buying stressful, which I truly appreciated. Cody also went above and beyond by moving a vehicle indoors so I could look it over comfortably despite the freezing temperatures and high winds. He made sure I fully understood the deal and then walked me through the vehicle so I felt confident using everything before leaving. I also want to recognize Tito and Ray in the finance department. They made that part of the process incredibly smooth, taking the time to explain each form clearly and walking me through everything step by step. Their attention to detail was impressive. Overall, this was unlike any car-buying experience I’ve had before. I never felt rushed or treated like just another number. Every associate I worked with, from sales to finance, clearly cared about delivering exceptional service. I can’t recommend Frank Leta Honda enough.

Leasing a 2021 Tiguan
I’ve driven Volkswagens since 2002. My very recent leasing experience was seamless thanks to Jason K. The Bommarito team was informative, efficient, and pleasant to work with from start to finish. Thank you, Jason Kresko!

Amazing Service Department
Chris Johnson in the service dept. was awesome! I had a major engine problem and talked to Chris who instructed me to bring my car in so he could look at it. To make a long story short, Chris and Hyundai stood behind their product and completely took care of my problem! Can’t say enough good things about Chris and Hyundai! Thank you!

Nicki was wonderful, I will recommend her to everyone I
Nicki was wonderful, I will recommend her to everyone I know that are in the market for buying a vehicle. Jarrod was also fantastic to work with. Both very personable and made the process very pleasant when it had been made dreadful from trying to deal with other salesmen at other dealerships. These 2 were excellent. I've never had a better car buying experience. I'd been to 4 other dealers who wouldn't budge on price for the same vehicle. I was able to drive my brand-new car off the lot for $6000 less than the competitors offered WITHOUT a single haggle!
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Joe at front desk was fantastic! Always smiling when we go in! Huge selection of cars too!
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.
