New Suburban
Found the new 2023 suburban silver grey suburban I wanted on cars.com at Webb?s dealership. Drove 177 miles in my son?s Sierra pick up where Jason answered all my questions and completed the sale. All employees and facilities at web where friendly, clean and professional. Jason made my purchase possible by keeping the Sierra at the dealership until my son could pick it up one week later after arriving from O?Hare airport. As a lifelong Chevrolet customer, I highly recommend Webb to everyone.

Exactly what I was looking for. Lots of trucks
After extensive searching I found a truck at summit auto center that matched my needs. After deciding to buy the truck, the whole process was actually easier than some local deals I have made. The condition of the truck is outstanding! At 6 years old it is in a condition that one would expect of a 1 to 2 year old unit. I am very pleased with the deal. A search for any trucks I may need in the future will start at Summit Auto Center

We came in late in the day with an unexpected emergency
We came in late in the day with an unexpected emergency car repair and were very happy with the service provided. Everything was great! Check in, our shuttle driver Vicky was so kind and even stayed late to take us home which we appreciated. The car was fixed in a short amount of time and shuttle driver back Ed also very nice. We've purchased and had our cars serviced from D'Arcy since 1990 and could not be more pleased! Thank you!

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😀

Best experience ever at a dealership
dealerships on how to treat customers!!!! This was the BEST dealership experience we've ever had in our lives!!! Chris Dargan was amazing!!! He was courteous, professional, knowledgeable, and treated us with the utmost respect. Chris never tried to overcharge us. Bert Dutcher was awesome as well!! Bert was upfront about everything and never once did he try to convince us to use their financing. Bert was professional, kind, personal and patient. The only bad thing about Bert was that he wasn't a "Dallas Cowboys" fan!!!! When you're ready to purchase your vehicle and you want to be treated with dignity, come to Rizza!!!
