Great customer service - Gabrielle
Excellent dealership with great customer service. Paul helped me out a lot with everything. I am a completely satisfied customer and will be visiting this dealership for all my needs on my impala.
Cindy Laser, Service Dept. - C. Weigel
I use Cindy exclusively, because her level of customer service is outstanding. I guess that being a woman, I like dealing with one. She is always extremely helpful. I have bought three new cars from Sullivan and with each car, I usually need her help me, because of the incredible technology, that is put into these new cars, that baffle me!
When Cindy is off, I always count on Geoff to help me. He too, is very patient, teaching me how to run some of the stuff.

Oil change, tire rotation, multi PT inspection+minor warrant - McElroy
Came in fo oil Change and tire rotation an a few minor problems. There was a rattle by the drivers side door that I couldn’t pinpoint. I expected to hear from them that they could not find it. But they did find it and corrected it. Trunk lid would not open fully. Corrected it. The tech was thorough. The service advisor was knowledgeable and courteous. They even washed the car. Got all the salt off. A fantastic experience. Thank you Bill Kay.
It's the little things that make a huge difference!! - DLG
I have been looking for a newer model car with a few features which were lacking on my 2012 Buick Verano. I definitely needed a rear camera, warning lights on the rear view mirrors, I needed the car to be 'dog friendly.'
I drove to Marquardt for an oil change and one of the Salesmen, Miguel Sanchez, approached me and very patiently went over the upgraded features on the 2015 Verano which I was looking at. As I was thinking of a vehicle with a higher sitting position and the 'feel' of a SUV, he offered me two test drives: one in the Encore (an overnight test trial), the other in a Denali which I drove home and back the next day without any pressure to purchase either model. I liked both of the cars I was shown; but having owned a Verano, I kept thinking perhaps I needed to test drive the newer model. It only took a drive once around the building and I was sold on it. Miguel answered many questions I had without wanting to be 'elsewhere.' Carey Lynch was present and gave me advice on leasing vs purchasing a vehicle because of my history of not wanting to maintain an aging car; and within minutes, she gave me prices to ponder! Then the leasing agent, Tim Holloway, explained the lease details in less than 10 minutes and answered a few questions that I was always curious about when leasing.
There are many extra benefits besides the red licorice snack jars when you buy from this dealership. A valet service, free car washes, a specific amount of time for included 'maintenance' and 'oil changes,' and friendly, unhurried service department personnel!!
Please stop in and visit this dealership! The waiting rooms on both levels are spotless and they have free sodas, TV, reading materials, and coffee!!
I will definitely return to Marquardt for any further purchases and I know from experience the 'wait time' for routine work can be excessive in some dealerships. Yet, not here!!
PS: Petsmart has a bucket and/or bench seat cover for your critter and the back seats in most models can be flattened for carrying a critter or a crate!!
Top notch service. - Carol O'Dell
Once again, had work done on my older GMC and was treated like a queen. Love the service from the time I made the online appointment, to dropping off the car, to the many courteous calls. Then picking up the car...the entire experience was excellent.
Thank all of you who did their part to make my experience an awesome one.
Excellent service! - Clarifierdd49
Steven Crane in the service department is excellent! He is polite, attentive, informative and truly cares. I would highly recommend any person requiring service on their GM vehicle to see Steve Crane in the Grossinger service department.
Awesome - mario1996
I like the way the service was , it was very respectful and it's a very helpful place I recommend it to anyone looking for good service and a car
Disappointed - Courtney
I went in for an oil change and asked to replace my 3 wiper blades
$82 later for just the blades if highway robbery
Took me for a ride for sure!
They need to mention the cost beforehand
Sevice department rip off - sparky24
My daughter took her Chevy in for repair, and they said she needed all new parts and they were burned out, We took it to another auto repair they said parts were fine , fixed a wire. This dealer tried to get $ 1150.00 off my daughter for parts that were in good working order. I believe they call it Fraud??No one could be that incompetent. Then tried to charge her $ 99. 00 for there lie of diagnosis.
DO NOT trust the night crew at this location - Joyful2018
Let me first say our experience with our Saleman and the daytime service department crew has always been pleasant. We have purchased THREE cars from this dealership and for the most part have been very happy.
Unfortunately , the night crew at within the Service Department steals the thunder of what I do believe is a great dealership. Every time we have had to bring our car in during the night shift we have experienced a problem and were treated HORRIBLY!
The night manager is anything but professional, they never call that evening with an update, they never finish their paperwork so when you call in the next day the girl/woman has to go looking for the paperwork and call you back with an update.
There is so much I want to share, but I will leave you with this...DO NOT TAKE YOUR CAR THERE AFTER 3:00PM! Again, we have NEVER had issues with the day time crew and the work they have done. The Night Crew and the Night Manager are not professional AT ALL!
Horrible customer support after the sale - Mchlhow
I am posting this review to inform potential buyers of the risks of purchasing a used Pre-Certified GMC car from Courtesy GMC-Buick in Crystal Lake. The issues that I experienced include management standing behind a car they sold, unable to fix basic problems (multiple visits per issue), and customer satisfaction (mostly dealer exec management).
The facts speak for themselves. I purchased a 2012 Yukon XL (65,000 miles) in August 2016. It has been in the shop 36 times (44-days total) for 16-problems in 16-months. Five of the critical problems were missed during the pre-certification of the vehicle (alignment, tires & rims, radio, steering, outside mirror). I paid for several key repairs and have spent approximately $3,500 out of pocket.
Once I switched dealerships (8 months ago), the issues were resolved. I attempted to work with the Courtesy Management (including owner) and that did not go well. The Courtesy Service Staff (all of the service reps were great including Mark O) really tried hard and once management got involved it got bad. I attempted to obtain the Pre-Certified Checklist (the pre-certified agreement says the dealer is to provide) and was not allowed to take it from the dealership (the finance representative would not provide a copy). In addition, the dealership used my extended warranty without my consultation and during the Pre-Certified timeframe.
I fully understand buying a used car has risk. This is the reason I purchased the pre-certified warranty and extended warranty. I have purchased used cars all my life and this is by far the roughest experience. This situation is fully documented and I can support all items listed above.
The reason I am posting now is that I had to take the car in again this month for a repeat problem that Courtesy attempted to fix earlier this year.
Worst service ever !!! - 123monia
Service is poor and no one is nice to you everyone I rude to you. When I drop my car off for service there is always issue after I fix my car.
Their customer service is really bad. I was told that... - veronruth
Their customer service is really bad. I was told that parts will come in within a week and then a week became weekssss and NO ONE CALL to let us know. We have to call back to find out. When we called, they can't find my order and told me to bring my car back so that they can check on the parts numbers, which they should given that i was there the last time and they looked at my car. Upon my request, they checked again and then FOUND my records and told me that part would take a few MORE WEEKS!!!!!
