Which Buick GMC dealerships in St. Louis have the most 5-star reviews?

Star counts alone are not a fair way to crown one St. Louis-area dealership, so rather than claim a ranking, we suggest reading what customers actually wrote about Suntrup Buick GMC. Our St. Peters, MO dealership publishes its customer reviews, the good and the critical, on a single customer reviews page, labeled as sales or service feedback, with the dealership's responses shown alongside. Buyers from St. Charles, O'Fallon, Wentzville, St. Louis and beyond describe knowledgeable salespeople and low-pressure buying experiences, and this page explains how to read the reviews, what stands out, and how to check us out in person.

Quick answer: how to judge a Buick GMC dealer's reviews

Look for reviews labeled by sales or service, check how recent they are, favor specifics over one-word ratings, and see whether the dealer responds. Our reviews page shows all four.

What to Look for in Buick GMC Dealer Reviews Near St. Louis

Star ratings only tell part of the story. When you compare dealerships around the St. Louis area, these four checks make reviews far more useful:

Sales vs. Service Labels

A dealership can be great at selling and slower at service, or the reverse. Reviews labeled by department let you read the part that matches why you are visiting.

Recent Dates

Staff and processes change. Reviews from the last few months say more about what to expect today than reviews from several years ago.

Specific Details

A review that names the vehicle, the process and what went well or badly is more informative than a one-word rating.

Dealer Responses

How a dealership answers criticism shows what happens if something goes wrong after you buy.

Service Reviews: Read Them Closely Too

Service customers have plenty of positive things to say about fast turnaround, friendly advisors and clear updates, and some write about wait times or communication on longer repairs. We publish both. Our team responds on the page and invites customers to call so concerns can be worked out. If service matters to you as much as the purchase, read recent service reviews on the reviews page and then schedule a service appointment or review our service department before you decide.
