Arlington Heights Buick GMC

We went to Sullivan because they participate in the COSTCO Car Program. Gabriel was great. He was so patient and helpful in obtaining our 2012 GMC Terrain. He went above and beyond the call of duty COSTCO Car Program. Gabriel was great. He was so patient and helpful in obtaining our 2012 GMC Terrain. He went above and beyond the call of duty to search for exactly what we wanted. When that couldn’t be obtained, he offered the option to order it directly from the factory. We couldn’t be happier with his helpfulness, determination and professionalism. We couldn’t have asked for a better person to assist us with our purchase. Gabriel is wonderful! We want to thank Gabriel (and Gerald in finance) once again for making this experience something we will not forget! We love our Terrain! We chose the right SUV! More

Would like to commend Geoff on excellent customer service. I was searching for a used Silverado or GMC Sierra and found one online at your dealership. It is highly unlikely that I would ever ventur service. I was searching for a used Silverado or GMC Sierra and found one online at your dealership. It is highly unlikely that I would ever venture out of my own community (Kenosha, WI) to make a large purchase as I am concerned about future service of vehicle etc.. But after meeting Geoff and other members of the dealership including Gerald I was put at ease about service due to the fact that they explained in detail the benefits of a GM Certified used vehicle. I can have it serviced at any reputable GM dealership. I will however consider traveling back to Arlington Heights for routine maintenance to keep my business where I feel comfortable and although set for a while in the vehicle dept. I will definitely return to Sullivan Buick/GMC for future purchases. Thanks again Geoff for not making this vehicle purchase a 'painful' experience as I have had a few in my years of car buying. A very satisfied customer! Ed Gramza More
