Is Group 1 Buick GMC South a good dealership?
A dealership is good when strangers say so and you can check it yourself. We are Group 1 Buick GMC South, long known as Beck and Masten Buick GMC South.
As of October 2026 we hold 4.3 stars across 4,983 Google reviews, and 77.2% of them are five-star. That is a high-volume, mixed record, since 13.9% are one-star, and the checks below take an afternoon.
Keep reading below, then schedule a test drive in Houston. Bringing your own numbers to the lot settles this faster than any spec sheet.
Reviewers say trucks are what we are known for
Truck selection is the subject our Google reviewers raise most. 524 reviews mention it, the most of any topic on our Google listing. People come here for trucks and say so in public.
In a July 2026 Google review, Claudia M. wrote: “I recently purchased a truck, and the entire process was incredibly smooth and hassle-free.” Claudia M. named the salesperson, Carlos V., and wrote that he kept in touch after the sale.
Here is what the reviews point to, so you know what to test:
- Trucks: Selection is the top subject by a wide margin. Ask to see the cab, bed, and drivetrain you want on a specific unit.
- People by name: Reviewers thank the salespeople and service advisors who helped them. Ask who will work with you and read what others wrote about them.
- Certified pre-owned: One July 2026 reviewer chose a certified pre-owned vehicle here and wrote that it cost less than at the other places checked.
How to read 4.3 stars when 692 reviews are one-star
A 4.3 built on thousands of reviews tells you more than a 4.3 built on dozens. Of our 4,983 Google reviews, 3,849 are five-star and 692 are one-star. The rest sit in between.
| Star rating | Google reviews | Share of total |
|---|---|---|
| 5 stars | 3,849 | 77.2% |
| 4 stars | 209 | 4.2% |
| 3 stars | 128 | 2.6% |
| 2 stars | 105 | 2.1% |
| 1 star | 692 | 13.9% |
Do not stop at the average. Sort our Google reviews lowest first and read a dozen. A pattern is easy to spot at this size. If the same complaint shows up again and again, and it matches what you plan to buy or service, weigh it. A one-off does not carry the same weight.
Then read the five-star reviews the same way. Look for dates, names, and details. A review that names a person and a vehicle is worth more than a line of praise.
Beck and Masten is our former name
Yes, Beck and Masten Buick GMC South is us. We are now part of Group 1 Automotive, and the old name still lives in customer language. 62 reviews on our own Google listing mention Beck and Masten Buick GMC North, the sibling store that carried the other half of the name.
You will see it in the reviews. A July 2026 reviewer thanked “Beck & Masten Buick GMC South” for a certified pre-owned purchase. Another, the same month, praised “Beck & masten Buick” for an oil change on an Encore.
So when you check us, search the old name too. Reviews under either name are about the same Gulf Freeway store at 12820 Gulf Freeway.
Ask for the price and your trade value on one specific vehicle
A good dealer gives you numbers on a vehicle, not a pitch. Pick one unit on our lot or site and ask for the full price and what we will pay for your trade. Then compare it with what you find elsewhere.
In a July 2026 Google review, Antoinette B. wrote: “He wasn’t pushy and was transparent with his price.” Antoinette B. added that the certified pre-owned vehicle chosen was more affordable here than at other places checked.
Here is what to put on the table:
- The documentation fee. Our advertised prices include a $225 dealer documentation fee, shown on each listing. Texas sets no dollar cap on the fee. A seller needs no filing with the state credit regulator at $225 or less, and has to file a notice and a cost analysis above it (Texas OCCC, 2024).
- Your trade. Texas charges motor vehicle sales tax of 6.25% on the sales price minus any trade-in allowance (Texas Comptroller, 2026). A real trade value lowers the amount you are taxed on.
- A number before you visit. Our Sell Your Vehicle tool takes a license plate, VIN, or make and model. The value it gives holds for seven days or up to 250 miles.
You can also start a finance application online. We offer loans and leases, and you can finish the purchase online or in the store.
Call the service department and see how it keeps you posted
You will meet the service department long after the sale, so test it first. Book by phone, in person, or online, then ask how you will hear about your car. We think the answer matters more than the coupon.
In an August 2026 Google review, Javier T. wrote: “Great customer service from service advisor Omar. The technicians serviced my truck quickly and wait was minimal.” That is a named advisor, a vehicle, and a wait time you can hold us to.
Our service hours run Monday to Friday 7:00 AM to 6:30 PM and Saturday 7:00 AM to 4:00 PM. We are closed Sunday. Our parts department supplies genuine Buick and GMC parts. Parts can be ordered online and picked up when we say the order is ready.
Check that we carry the Buick or GMC you want
We sell two brands, Buick and GMC, so confirm we have your model before you drive over. That is a simple check, and it saves you a trip.
On the Buick side we list the Encore GX, Envista, Envision, and Enclave. On the GMC side we list the Terrain, Acadia, Yukon, Yukon XL, Canyon, Sierra 1500, Sierra HD, and Sierra Cab Chassis. The electric choices are the Sierra EV and the HUMMER EV pickup and SUV.
We also sell used vehicles from Buick, GMC, and other brands. Sales hours are Monday to Thursday 9:00 AM to 9:00 PM, Friday and Saturday 9:00 AM to 8:00 PM, and closed Sunday.
A one-afternoon checklist for judging any dealership, ours included
Run the same four checks on every dealership on your list. They work for us and for anyone else, and each one points to something you can verify without taking a word from us.
| Check | What good looks like | Where you verify it |
|---|---|---|
| Reviews | Named people, dates, and a repeated subject you care about | The dealership’s Google listing, lowest ratings first |
| Price | A full price and fee list on one specific vehicle | The unit’s listing and the written quote |
| Trade value | A number from a tool or appraisal with a stated time limit | The online trade tool and the appraisal in the store |
| Service | A named advisor, easy booking, and updates while the car is in | One phone call and the service reviews |
A good dealership leaves a trail you can read
Our record is high in volume and mixed in score, and we would rather you read it than take our word for it. The 4.3 rests on thousands of voices. The trucks, the named people, and the service updates are what those voices repeat.
Check the one-star reviews, ask for the numbers on one vehicle, and call service before you sign. Trust the trail you can check.
