Mark Allen Buick GMC

Best dealership I’ve ever went to. They mean it when they say “Come in, let’s do business!” Definitely recommend.

Very nice and courteous. And when buying a new vehicle not pushy. I'm definitely buying my next vehicle there.

My NEW car has cut marks from the no-choice sloppy installed door guards-Beware!

Just bought a new buick here. Great service. Racheal worked hard to make sure we bought wwhat was best for Me. And Joe worked with us on financial status. Great people. Beautiful facility.

Very pleased. They are layed back no hassle yet very helpful.would do business with them again.

Great experience! Our salesman, Lindsey, was great to work with and the buying process was very streamlined and stress-free.

They do a great job! Always fast and courteous. I will go back for all my service work.

Where do I start? Before we could get out of our car, the sweetest salesperson greeted us. Her name is Jordan Dewey. She showed us the cars we wanted to look at, explaining all the bells and whistles that they had. We wanted a certain color and interior and she located one for us. Everyone at that dealership was very kind and professional. Jordan walked us thru all the apps and connections and once again all the bells and whistles that car has. She was so kind and understanding as we are senior citizens and not so tech savvy. We bought a GMC Arcadia. We absolutely love it. We drove the few extra miles to do business at Mark Allen Buick & GMC in Collinsville. Please look up Jordan Dewey. You'll be glad you did.

The best experience I’ve ever had in a dealership. Friendly people and great customer service! Lindsey was great!

A great experience overall. Everyone was so kind and helpful. I would highly recommend this dealership to anyone. We will definitely be back ! We came in to purchase a used car and left with a new car and a great deal .
