Agent Keith greeted me when I pulled in for service.
Agent Keith greeted me when I pulled in for service. He asked me to step inside and would be there in a minute after checking my VIN and mileage. He helped me locate my rewards number on my phone and went over the prices for my oil change, tire rotation and new battery. Later when I was in the waiting area, Keith informed me that 30,000 mile maintenance needed attention. I agreed to the two services recommended and was still out of the dealership in around two and a half hours. Keith processed my 10% discount and informed me of a $20 rebate for the new battery. He explained the process for requesting the rebate online. I highly recommend Garber Chevy for their sales and service. I have bought three cars here and am willing to drive the seven miles to Garber even though there are Chevy dealers in Lansing, Ill where I live that I no longer deal with if possible. The other dealership will always ask me three to four times if I would like to trade my car in or do I want to look at new car models. I don't like that, if I want to look at a car or want a trade-in, I'll ask. Go see Garber and you will be surprised!
The hidden gem Buick Encore GX
I know that here in Northern California, Buick isn't a very popular brand, but that means I was able to get a stunningly good deal on my new '23. I traded up from a low mileage '18 Buick Encore (not GX), and at the time of the transaction, it had a remarkable trade value. My dealer did a outstanding job on pre-sale prep and delivery. My sales rep answered my every question. I enjoyed the prior vehicle, and feel this new one will give me the same kind of driving experience. My added safety feature is the front accident/pedestrian avoidance and lane keep assist. I haven't had to use either yet, but feel good about having them aboard. This Buick strikes me as a hidden gem, full featured but still available at a price point that blows the other comparable Asian built imports out of the water.

This is the third S-class Mercedes I have purchased from
This is the third S-class Mercedes I have purchased from Mercedes-Benz of Westmont and I could not be happier. Going through the purchasing process was a delight because Kimberely Cager, my Sales Rep, and the sales management team made me feel better than just a valued customer. The real test, however, came when driving the new 2025 Mercedes S580. The supreme road handling and comfortable seating were nothing short of spectacular, and the many options like the integrated toll system (driving through tolls of different states has become hassle free), Apple CarPlay, and several driver-assist features has enhanced my driving experience. While understanding how to use and benefit from the many new features and options was a little daunting, Kimberely and the Product Concierge, Damir Oliynyk, have eased my doubts, and I?m looking forward to a long multi-state road trip.

The car has been very reliable , I have replaced the water pump, timing belt, and done brakes and oil changes, I also fixed the manifold/valve cover issue. These were all normal Repairs . I am pretty good with maintenance, so that is key w this car. If you just drive it, don’t change oil or fluids then like any car you will have problems . This one has been very good .

John P. and Zach M. work so hard to accommodate my family?s schedule with shuttles and getting our vehicle in and out quickly when needed. They recently facilitated a cracked windshield repair along with other routine maintenance the GMC needed. Hare truck and its technicians/mechanic?s have maintained and repaired my GMC Yukon that I purchased from Hare Chevrolet 8 years ago. Over 200K on this vehicle and going strong. Good pricing, dedicated professionals and easy to get to location.

They found me a 2024 Cadillac XT4 and I love it. My husband and I switch to Napleton Cadillac because they have wonderful followup and my salesperson Jimmy was very helpful and got us in and took great care of us. Isaac made the transaction seamless. Now Napleton has two Cadillac owners for life. It was a wonderful experience at Napleton Cadillac in Oak Lawn.
Dependable If Maintained
it is 2023 and it has 146,000 miles on it with no major repairs. I change oil ever 5K miles and do all scheduled maintenance. My wife loves it. She can carry lots of her stuff and it easily converts to handle passengers.

Purchase of a certified Buick Regal
I live far from this dealership but they had exactly what I was looking for. The whole experience was very favorable . Everyone I has contact with was very professional and courteous. The salesman I worked with Joe Kendall was excellent. The day after the purchase I noticed that a light strip was missing on one of the outside mirrors. The service dept fixed it. In my opinion they are a top notch GM dealership . Keep up the good work😀
I bought my 2018 essence in January 2020.
I bought my 2018 essence in January 2020. It was a rental car with 24,000 miles when I bought it. 34k new, I got it for $17,600. It now has 102,000 miles and I hope to have it for at least 5 more years. Runs and feels brand new. Hard to believe. I still feel happy just getting behind the wheel. So comfortable and fun to drive. Only change the oil and new tires. Not one mechanical issue. I'm afraid I'll never have another car like this one.

Great job Penske Genesis
The staff at Genesis of Noblesville are fantastic. Laura McClain Is our salesperson. He between me and my wife, Laura has sold us 4 or 5 cars. She is the greatest. Same with Andy and Troy that handle the finance. Always helpful to get us the best rate available as well as protect our investment with good warranties. I use the Penske service department to keep my G80 in tip top shape. They are efficient, cost effective and great comnunicators when it comes to what your car needs and the best cost that they can provide for service and repairs. I highly recommend Penske Genesis for your auto needs.
For a car made in China, with their reputation for
For a car made in China, with their reputation for putting out shoddy products and looking at their buildings and roads that's falling apart as we speak, I was totally surprised at the quality built into this car, not knowing at the time of purchase that it was made over there, which would have made me pass on buying it. But we are talking GM here, that built the plant in Shanghai, who took every part over there just to use their labor only to assemble it, and they did an excellent job. I figure that GM pays them better than all other jobs in that country and they don' t want to lose that job, so they do the best that they can when putting it together. We are at 105,000 miles now, and did all the oil changes and did go through the hundred thousand mile checkup and all fluids changed, and it has yet to have anything to go wrong with it except for changing out the 5 year gel filled very expensive battery *at 5 years on the dot, and the second set of tires. Even still has the original front pads on the brakes, but due to my real easy driving and feathering them coming up to stop lights, trying not to let the stop/start system engage at full stop, and have been doing an excellent job in timing lights and breaking one law by doing 'rolling stops' at stop signs with no cross traffic in sight. I'm a person that drives a vehicle until it rots down, like I did my '84 Toyota diesel pickup that I put over 800K on it until finally the box frame under it rusted in two, forcing me to park it forever, with the engine still running in it. And with this car I'm shooting for the same mileage before it falls apart just from so many miles on the body.

Buy from Wesley Radford
Purchased a new Avalon from them today. Wesley Radford was my sales rep and the entire process was an extremely pleasant experience. Wesley was patient with me and did not give any hard sell tactics. There was a slight glitch due to my misreading some info and Wesley rectified everything to my great satisfaction. Everyone else in the process was polite and helpful. Lombard Toyota is the place to go and Wesley is the guy to ask for.
Just what I was looking for
This car met all our needs. Love the color and the interior design. Alloy wheels are very nice. Engine performance is excellent. Ride is very smooth and quiet.

I just purchased a car from Castle Hyundai of Oak Lawn,
I just purchased a car from Castle Hyundai of Oak Lawn, and I couldn’t be more grateful for the experience. From start to finish, the team showed true professionalism, care, and integrity—qualities that can be hard to come by in the car-buying world. Now I truly understand what they mean when they say “Drive Happy!” Jim (Sales Manager), Nick (Sales Consultant), Brennan (Internet Representative), and John (Finance Manager) were an absolute pleasure to work with. They went above and beyond to make sure I felt informed, respected, and supported throughout the process. They were transparent, never pushy, and always willing to answer my (many!) questions with patience and honesty. It was clear that they genuinely cared—about the car, the deal, and most importantly, about me as a customer. They didn’t just meet expectations - they exceeded them. The entire process was smooth, respectful, and even enjoyable. These are good people who take pride in doing right by others. Thank you to everyone at Castle Hyundai of Oak Lawn—you didn’t just help me get a great car, you made the whole experience one to remember. You went the extra mile (pun absolutely intended) and because of you, I now Drive Happy!

Minor problems and I LOVE IT.
I bought it used fron Carvana with 49000 miles on it. When it had around 100,000 miles on it i had to replace the middle 2 coils. I did it myself for $100 each. Took me 30 minutes on each one. It now has 137000 miles on it and the check engine light has been on since 110000 indicating a "failing turbo". It shows no signs of failing and continues to run good. just drove it from Florida to Texas and back (1800 miles) It ran good. I have had 4 Buicks and very little trouble with them. I would definitely recommend this car. Beautiful and easy care- just change oil ecery 5000 miles and it keeps going.

Knock on Wood. No problems like the other reviews
I leased this 2017 Encore in 2017 after the lease was up I bought it. Now in 2024 I am just putting tires on it. I put a new battery in last year. That's it! I change the oil. I have read the bad reviews and am surprised. To be fair I drive in town and 6000 to 7000 miles a year.
