BEST DEALER EXPERIENCE I HAVE HAD IN THE PAST 1 YEAR, BUYING MULTIPLE CARS IN ST. LOUIS!

Starting with Roger Silva who I initially spoke with, Walter who was very patient with me in finding the right car I needed to the finance managers, they have the best team working here. Everyone was very courteous, patient, and helpful. Best buying experience: I spent less than 30 mins in the dealership; everything was done online. I love this new way of doing business. Unlike many dealerships where it's all haggling and going from one person to another, waiting for hours, OFallon, Buick GMC had none of that nonsense. More
The Team at Ofallon Buick/GMC are top notch. It was well worth me going out of my way of an hour to buy from this dealership. Roger my sales person, was very good at explaining the 2024 AT4 and It was well worth me going out of my way of an hour to buy from this dealership. Roger my sales person, was very good at explaining the 2024 AT4 and showing all the features during the test drive. Finance guys had me in and out in no time. I would send my friends and family to these guys. Happy New Year More

Seems like there is a huge disconnect between service writers and the techs. Last visit brought my vehicle in for a bunch of maintenance (no issues) and a state emissions test. Service did all the mainte writers and the techs. Last visit brought my vehicle in for a bunch of maintenance (no issues) and a state emissions test. Service did all the maintenance before the emissions test, well they set a check engine light and now vehicle would not pass test. They did not tell me what happened and just let me pick up vehicle. Got home and then realized I didn’t have a passed emissions test and had to call dealer back. I was just told to drive about 100 miles and swing back in. Why would you not perform emissions test first!? Why would dealer not tell me or try to reset all emissions monitors so I don’t have to come back?! This is not the first time I’ve had to bring my vehicles back after having dealer services. i have 2 vehicles serviced there. The positives are they are super nice and super convenient. More
