What to look out for when choosing a Buick GMC dealership

Pressure and misleading sales tactics are a complaint buyers raise about dealerships. What does a salesperson say when you tell them you need more time to decide?

Another complaint in those reviews is long service waits and hard-to-get appointments. Among the Google reviews of Gay Buick GMC is one from James N., dated April 2026: “They didn’t do anything for a week, then called with an estimate on day 8. Got it back after another week. I had even made an appointment so it should have been looked at the day of the appointment” When you book a service appointment, how will the dealer tell you when work on your car starts?

The same reviews also complain of no loaner or ride while the car is in service. August 2025 brought a Google review of Big Star Buick GMC from Amy D.: “I asked for a loaner car because I do not have a way back-and-forth to work and I was told they did not have one. I was also told that they would get my car in as fast as I could. No date of service.” Does the dealer have a loaner or a ride available on the day you drop off your car?
