I Of course, I have the email where they stated "TOTALLY FINE" with not making payment.

The car buying experience can be stressful and down right intimidating but Marquardt makes it…read moreseamless, relaxed, and so pleasant. I messaged ahead with what car I wanted to look at (yea, I was worried about the dreaded online bait and switch). I was contacted by a sales rep who let me know it would be ready for me to test drive. I got there and wouldn't you know it, it was washed, ready and waiting up front. The exact car. I met the most wonderful, friendly, knowledgeable, not pushy and not in the slightest bit the stereotypical cheesy car sales person. Deanna was AMAZING. We went for a drive and it was more like riding around with a friend. We got back and paperwork stuff simple. Everyone bent over backwards and was so straight forward. There wasn't any of the hidden dealership fee games or the "oh yea, and then..." driving up a price. I never felt any pressure to get pushed into anything out of my price range. Deanna and the team here are top notch. If you're thinking of a new car, come check this place out.

I was truly steered by God to this dealership. I am now a customer for life. I found them while…read moresearching for a new Hummer ev on the GMC corporate website. I can with great confidence declare that Marquardt GMC and their entire team are truly the pinnacle of what they advertise "Expect, honesty, integrity and transparency." Frankly, in their quest for professionalism and value for the customer they exceed all expectations. I say this after a lifetime of experience in buying cars as I approach age 70. Please know it's a smaller, family run type businesses. Note that is has successfully been in business since 1950. That is a testament that they are truly best in class at all that they do. The buying process always seem long, but they go through the effort to make you feel at home, address every concern with care and consideration and make the process comfortable and enjoyable in contrast to the adversarial approach others often take. My wife and I genuinely appreciate the blessings to have found this place, the people, and so happy with our new GMC Hummer Pickup. I can't speak highly enough about Dave (Sales Mgr) and Tim M, Sales Associate. Thank you very much for the experience, the vehicle and all of the continued support.

## 82-Day Registration Failure, Legal Exposure, and Total Management Abandonment…read more I purchased a new 2025 Lexus RX 500h from Lexus of Highland Park on April 15, 2026. While the sales associate handled the initial showroom transaction politely, the post-sale administrative handling and upper-management conduct fell completely below basic industry, legal, and consumer standards. **Improper Plate Transfer:** At delivery, dealership staff transferred and mounted my Nebraska personalized plates ("J STYLE") onto the new vehicle. They assured me this was legal, despite my explicit objections that the plates belonged to my trade-in vehicle. **82-Day Loss of Legal Use:** Due to administrative mishandling and an original title reportedly lost in transit, the paperwork did not arrive until late Friday, July 3, 2026. Because of the holiday weekend, the vehicle could not be legally registered until Monday, July 6, 2026, depriving me of lawful use for 82 days. **Dismissive Management:** Sales Director Julio Gomez characterized an 82-day delay as "normal" and recklessly advised me to simply "show a police officer the bill of sale" if stopped while driving across state lines. **Documented Financial Losses:** Operating out of state with mismatched registration created serious legal, citation, and insurance risks. I was forced to cancel a planned road trip, incurring $1,800 in nonrefundable airline and travel expenses, while continuing to pay insurance and monthly loan installments on a vehicle that had to remain parked. **Broken Executive Commitments:** Mr. Gomez acknowledged the failure and promised a goodwill compensation package once the paperwork arrived. After the paperwork was received on July 3, Mr. Gomez, Director Julian Keller, General Manager Benjamin Nusinow, and Owner/Dealer Principal Alan Nusinow ceased all communication. They refused to answer calls, return emails, or honor their commitment. A luxury-car buyer should never face months of legal vulnerability, out-of-pocket financial damage, and complete abandonment by ownership once the funds have cleared. This matter has been escalated to Lexus Corporate and formally submitted to the Illinois Attorney General's Consumer Fraud Bureau. Buyers--especially out-of-state customers--should exercise extreme caution before trusting this dealership's administrative office and executive leadership. -- Jerry E. Johnson

Conveniently, for him, he informed me at that very moment that it was being marked up $10K for inexpensive sealants and a half body PPF job. I asked him if we could negotiate to include a full body PPF as this was a collector's item. He went silent on me and sold it from under me. I think arithmetic is not his forte, as that would have added more margin for them. Bless his heart. Thank the universe that he's not in the finance department ;) Lexus corporate would agree that this is not Omotenashi, no matter what 'master' certification he claims to have. Demerit number one. I wrote to a sales manager, Kevin Bennett, to assist me. I explained what had happened, and was told that management would assist me from here. Kevin told me that he had two LC's inbound, neither reserved, and that the policy would be to begin taking offers on these as soon as they arrived in Chicago. I have recorded calls on all of this. Maybe this can be some weekend listening for their GM, Benjamin, on how to not run a business. Ray would certainly have done things differently. Kevin told me that all offers would be considered, even though I had already been promised a unit with my previous deposit link. He told me that they wanted to look at local buyers (I have a residence near Bartlett), and that a trade-in would be important (and luckily, I had a 2024 Lexus to offer up as tribute). For weeks, I would not be able to reach Kevin. Voicemails. Emails. Asking staff to put him on the phone. If things couldn't get more unprofessional, Kevin pawned me off on Mike Afanasyev. I politely declined to engage Mike, as I had spent hours already with Kevin. He had assured me that I would be able to place my offer once the LC arrived in person, and that he would assist me here on out...right?! Oh, Kevin. You're special. When I finally got Kevin live on a call last week, I told him that it had been confirmed to me that the car had arrived. I needed the appraisal done on my 2024 Lexus in order to submit my written offer on the LC. This was all presented as a formality, and I was happy to go along with it. I got him the VIN and a dozen photos of my car same-day since he suggested that we do it over email instead of in person in their dealership last Friday. Demerit two for ignoring me for the last five days, Kevin. If management can't tell a transparent and honest story, they shouldn't be have their position. I've managed teams from 5-500, and you would never last a week at one of my companies. It all makes sense now as to why you wouldn't meet me last week. You couldn't look me in the eye to tell me what you had done. To nobody's surprise, Mike Afanasyev texted me today, to tell me that the LC had sold. In the spirit of being a stereotypical car salesperson, lacking tact on all fronts and in desperate need of any commission, he tried to get me to buy a 2022 car that I've never once expressed interest in. Yuck. Demerit number three. You know what they say about three strikes and being out: Lexus of Highland Park is out of touch, out of ethics, and out of a five-star review. I expect some Android response from them, because they are a heartless and mindless operation. So let this factual recap be a cautionary tale to anyone considering a purchase or lease from Lexus of Highland Park: don't do it. Take your money to McGrath or Fields. You'll be so happy that you did. You can't teach someone to live with good character. It's a personal choice, and I haven't met a single individual from this dealership with any. RIP, gents.

Everytime you come in for an oil change they tell you about yet other very expensive things you "must" do.

After thoroughly inspection the technician named Adrian stated that he will need to replaced the strut due to leakage. That being said, they provided a courtesy vehicle, allowing us to carry on with our day at no extra charge, which made things much easier for us. Whoever completed all the work on the vehicle, did an amazing job. The service at Karl Knauz is truly impeccable. From the moment you arrive, you're treated with professionalism, transparency, and genuine care. Kristy from service department is knowledgeable, attentive, and takes the time to explain everything clearly, making the entire experience seamless and stress-free. It's rare to find this level of service and attention to detail...exactly what you expect from the BMW brand. Highly recommend.

I took it to a third party mechanic who removed the duct tape, inspected and installed two clips to secure part properly.
