Mark Allen Buick GMC

Excellent service in a timely manner. I’m grateful for Mark Allen and what he stands for.

great job -- very professional and great communication. Clean area. Receptionist was friendly and so was the salesperson

Always a great experience when I take my car to Mark Allen. Tech and service center employees are knowledgeable and fast.

Great service, oil change, tire rotation, and fuel filter replaced. In and out in quick time.

The total experience of all departments has been fun and enjoyable and very friendly to work with

When I called to make the appointment for an oil change, I had several other small things to ask about. The person asking the questions was very polite and asked good detailed questions. When I came to pick up the truck they went over every thing from my list and explained how each item was resolved. I really liked that. Great customer service.

Our entire experience was very good. Gary was a patient and knowledgeable salesman. Everyone at the dealership was very pleasant.😃

Quick service, clean waiting area. I do wish they vacuumed and washed my car like they did in Plano.

We have bought many new cars over the years and this was by far the absolute best car buying experience we have ever had! We were totally blown away by every person we worked with. We know where we will be going for our next car. Mark Allen Auto Group.

I didn’t realize car shopping could be a fun experience until I visited the Mark Allen dealership in Collinsville. Everyone we dealt with was fantastic. We laughed, high fived, and felt welcome not just another customer. We will absolutely go back for our next vehicle purchase!
