Mercedes-Benz GLS interior and tech: what Austin drivers get
Mercedes-Benz of South Austin, at 10900 S I-35 Frontage Rd, Austin, TX 78748, has 4.6 stars across 830 Google reviews (Google, 2026). Buyers who have settled on a GLS usually want to see the cabin before they drive it, and this store lets you judge the seats in person, then handle the trade and the financing in the same place. The GLS seats seven in its main trims, and that is the part to judge in person.
Keep reading below, then schedule a test drive in Austin. Bringing your own numbers to the lot settles this faster than any spec sheet.
What does the Mercedes-Benz GLS interior give Austin drivers?
The GLS 450 4MATIC®, GLS 580 4MATIC® and AMG® GLS 63 SUV each seat seven, with six seats available as an option, according to Mercedes-Benz’s published 2026 specifications. The Mercedes-Maybach GLS 600 SUV is the exception, seating five with four as an option. For a family that needs seven seats, the three seven-seat trims are the ones to sit in. We sell new GLS models, so you can compare the trims side by side before you decide.
How many people fit in the GLS, and how do the second and third rows work?
On the GLS 450 4MATIC®, GLS 580 4MATIC® and AMG® GLS 63 SUV, first-row legroom is 40.3 inches, second-row legroom is 41.9 inches and third-row legroom is 34.6 inches. Those figures are the same across the three seven-seat trims, so choosing between them does not change how the rows feel. The Mercedes-Maybach GLS 600 SUV gives its second row 43.4 inches of legroom and carries 18.4 cubic feet of maximum cargo. The seven-seat trims carry 84.7 cubic feet.
What seat comfort and cabin features come with the GLS?
Seat comfort in a GLS is best judged on a test drive rather than read from a spec sheet. Sit in the front row and then the second row in each trim you are considering, and check how the seat fits your height and your passengers. Start with the trim that seats your family, then judge the seat itself. Bring your passengers, because a seat that works for you may not work for the child or adult who rides behind you.
How do the MBUX screens and voice control work in the GLS?
The screens and voice control are best judged on a test drive, with the infotainment and climate controls on your list. The money side is easier to settle before you drive. Our secure finance application is online, and we offer both financing specials and leasing specials, so you can compare the two before you visit.
In a December 2024 Google review, Vanessa M. wrote: “I went in to trade my Tesla for a pre-owned one and had an amazing experience with Vince. He truly rolled out the red carpet and made sure I was taken care of. He helped me get the car I wanted at a fair and competitive price, given the nationwide inventory. I enjoyed his service so much that I’m buying a second car from him.”

Frequently asked questions
What are the differences between the GLS 450, GLS 580 and AMG® GLS 63 interiors?
The three seven-seat trims share the same seat count, the same row legroom and the same 84.7 cubic feet of maximum cargo. The trim you choose changes the price and the power, not the rows. The AMG® GLS 63 SUV adds 603 horsepower and 627 lb-ft of torque, according to Mercedes-Benz’s published 2026 specifications.
Does the Mercedes-Benz GLS come with a warranty?
Mercedes-Benz’s 2026 warranty booklet lists a basic warranty of 4 years or 50,000 miles for the GLS line. That coverage applies to the whole model line, so it reaches the GLS 450, GLS 580 and AMG® GLS 63 alike. Ask the desk how that term fits a lease before you sign.
