Set your Mercedes-Benz GLS budget first, then pick new or certified in Austin
Compare GLS offers by the out-the-door total, not the sticker price, because state sales tax, title and registration fees and any dealer-installed options all add to it. Start with the price on the window sticker, then add each line that follows it.
Texas adds more than the sticker. When you buy in Travis County or the surrounding area, the total can include state sales tax, title and registration fees, and local county registration fees, such as Travis County’s local registration fee of $11.50. Ask for the full breakdown before you sign. Get a written breakdown covering the base price, dealer-installed options, window tint or protection packages, local inventory tax, state sales tax and registration.
The store sits on the I-35 frontage road in South Austin, ZIP 78748. Sales hours are 8:30 AM to 7:00 PM Monday to Friday and Saturday from 8:30 AM until 6:00 PM. Sales is closed Sunday. Bring your budget and your list of GLS trims to that visit.
Check each Mercedes-Benz GLS trim’s MSRP and seating before you visit
Each GLS trim has its own MSRP, seating, cargo and towing figures. For the 2026 model year, the GLS 450 4MATIC® SUV starts at $90,250, the GLS 580 is priced from $116,150, and the AMG® GLS 63 SUV is priced from $151,050, according to the manufacturer’s published figures.
All three seat seven, with six seats optional, and each tows up to 7,700 lbs. Each carries 84.7 cubic feet of maximum cargo. The Mercedes-Maybach GLS 600 SUV seats five, with four seats optional, and also tows up to 7,700 lbs. Its MSRP is not published, so check the current price with the store before you set a budget for it.
Compare the trims on the number that matters to you. If you carry three children, seven seats matter more than a cargo number. If you tow, check the 7,700 lb rating on the exact trim you plan to buy.
Add Texas sales tax and fees to the GLS price you compare
Texas adds motor vehicle sales tax plus title and registration fees to the GLS price, and Travis County adds a local registration fee. Each line changes your total, so add them before you compare two offers.
On a GLS purchase, Texas charges motor vehicle sales tax at 6.25 percent of the sales price after any trade-in allowance is subtracted (Texas Comptroller of Public Accounts, 2026). Your trade-in lowers the amount taxed, so a trade-in with a fair allowance reduces the tax you pay.
The title fee in Travis County is $33 (Texas Department of Motor Vehicles, Motor Vehicle Title Manual, 2026). The standard fee for a car or lighter pickup is a base registration fee of $50.75, plus $1 for TexasSure, shown on the renewal notice as $51.75 (Texas Department of Motor Vehicles, 2026). Travis County’s local registration fee is $11.50 (Texas Department of Motor Vehicles, Texas Registration Fees fee chart, Fee Chart 1C, 2026).
Your real total depends on your trade-in, your options and the fees on your written breakdown.
Choose a new or certified pre-owned GLS by the warranty each carries
A new GLS carries the maker’s new-vehicle warranty, and a certified pre-owned GLS carries the Certified Pre-Owned program’s inspection and warranty. Pick the one whose coverage and model year fit your budget and how long you plan to keep the vehicle.
The new-vehicle basic warranty for the GLS-Class is 4 years or 50,000 miles (Mercedes-Benz USA, 2026). A certified pre-owned Mercedes-Benz qualifies only if it is a model 6 years or newer with less than 75,000 miles and passes a 165+ point inspection, and the Certified Pre-Owned Limited Warranty adds 12 months of coverage with unlimited miles (Mercedes-Benz USA, 2026). The 165+ point inspection applies only to certain certified pre-owned vehicles with internal combustion engines (Mercedes-Benz USA, 2026).
Every Certified Pre-Owned Mercedes-Benz comes with a certification process, 24-hour Roadside Assistance, and a one-year unlimited-mileage warranty that can be extended for up to two more years, at Mercedes-Benz of South Austin. Certified Pre-Owned vehicles are backed by the remaining 4-year/50,000-mile New Vehicle Limited Warranty. Once that expires, the Certified Pre-Owned Limited Warranty goes into effect, providing an additional 12-months of coverage with unlimited miles. If you have broken down more than 100 miles from home, Mercedes-Benz will reimburse your travel expenses, up to $300 per day for three days (Mercedes-Benz USA, 2026).

One customer described the trade-in in an April 2025 Google review. In a 5-star Google review from April 2025, Grant H. wrote: “Had an excellent experience purchasing a Mercedes from Justin at South Austin. I came in on my day off, and the whole process was smooth and straightforward. Got a great price for my trade-in, and Justin made everything easy from start to finish. Drove away with a beautiful car for my wife—couldn’t be happier. Highly recommend working with Justin if you’re in the market for a new ride!”
What should you check on a Mercedes-Benz GLS test drive in Austin?
Ask the store to have a GLS ready before you arrive, and check its hours first. Sales hours are 8:30 AM to 7:00 PM Monday to Friday and Saturday from 8:30 AM until 6:00 PM, and Sales is closed Sunday.
Ask for time in the third row, because the third-row seat is the tightest space in the GLS. Legroom is 40.3 inches in row one, 41.9 inches in row two and 34.6 inches in row three on the GLS 450, GLS 580 and AMG® GLS 63 SUVs (Mercedes-Benz USA, 2026). On the Mercedes-Maybach GLS 600 SUV, row two has 43.4 inches and the cargo area is 18.4 cubic feet, so the Maybach trades third-row seats for a larger second row.
Contact the store ahead of time to confirm a GLS is pulled up and ready for a third-row and driving evaluation. Ask for the trim and the seating layout you plan to buy.
Get the out-the-door price for a GLS in writing before you sign
Ask for a written out-the-door price that lists the base price, dealer-installed options, any window tint or protection packages, taxes and registration. A verbal number is not enough to compare two dealers.
Before you sign, check each line against the fee figures in the earlier sections. Ask the dealer to explain any line you do not recognize.
