How much is a new Mercedes-Benz GLS before taxes and fees?

The 2026 GLS 450 4MATIC® SUV starts at $90,250 before tax and fees, according to Mercedes-Benz USA’s published figures. The same figures list the GLS 580 4MATIC® SUV at $116,150 and the AMG® GLS 63 SUV at $151,050 for the 2026 model year. At Mercedes-Benz of Westwood, we sell new Mercedes-Benz, including the GLS, so these maker figures are where a new GLS price starts. The state charges come on top of them.

What changes the price between GLS trims and options?

The trim sets both the power and the starting price. The 2026 GLS 450 4MATIC® SUV makes 375 hp and 369 lb-ft of torque, the GLS 580 4MATIC® SUV makes 510 hp and 538 lb-ft, and the AMG® GLS 63 SUV makes 603 hp and 627 lb-ft. Starting prices rise with each step, from $90,250 to $116,150 to $151,050, and options stack on top of those figures. On the AMG® GLS 63 SUV, the Executive Rear Seat Package PLUS is an extra-cost package priced at $3,550 rather than standard equipment.

What does a pre-owned or certified Mercedes-Benz GLS cost near Westwood?

A pre-owned or certified GLS is priced car by car. Its price is set from the individual vehicle rather than from a maker’s starting figure. At Mercedes-Benz of Westwood, we sell pre-owned vehicles, so the figure to compare is the price on the specific car. A used GLS is priced by its model year, trim, mileage and condition. Add the same Massachusetts sales tax, title and registration charges to a pre-owned price that you would add to a new one.

What Massachusetts taxes and fees come on top of a GLS price?

A GLS sticker price is not the out-the-door price. Massachusetts taxes a vehicle bought from a registered dealer at a 6.25% sales tax rate (Massachusetts Department of Revenue, 2022), and title and registration charges come on top of that. Massachusetts treats a dealer’s separately stated document preparation fee as part of the sales price, so the 6.25% sales tax applies to it (Massachusetts Department of Revenue, Directive 14-1, 2014). That fee cannot include any fees paid to the RMV. The Massachusetts RMV charges $75.00 for a Certificate of Title (Massachusetts Registry of Motor Vehicles, Schedule of Fees, 2025). A dealer’s separate title preparation charge is capped by statute at $5 per transaction (Massachusetts General Laws, Chapter 90D, Section 33, 2026). Ask for each line of the out-the-door total, and check any title charge against that $5 cap.

Can a Westwood buyer finance or lease a Mercedes-Benz GLS?

Yes. At Mercedes-Benz of Westwood, we offer new Mercedes-Benz financing, pre-owned car loans and Mercedes-Benz leases. Our secure online finance application says you get approved instantly. Settle the base price and the state charges first, then compare the monthly payment on that full total. A lease and a loan carry different terms, so ask for the monthly payment and the terms in writing before you sign.

How much will Mercedes-Benz of Westwood give for a trade-in on a GLS?

The offer on a GLS is set on the specific car, by its model year, trim, mileage and condition. Across the used market, the Manheim Used Vehicle Value Index stood at 212.9 in June 2026, up 2.1% year over year (Manheim, 2026). That is an index for all used vehicles rather than a GLS figure, and it shows the wholesale value that a trade-in offer is measured against.

What do Mercedes-Benz of Westwood customers say about its pricing and sales process?

How Mercedes-Benz of Westwood offers financing and leases on a GLS

The price you pay for a GLS is the sticker, plus the state’s charges, plus the way you finance it, so the payment choice belongs in the comparison from the start. Mercedes-Benz of Westwood has 4.5 stars across 4,046 Google reviews, and 82 in 100 of them are five-star (Google, 2026). Because the sticker leaves out the state’s charges, a buyer who arrives knowing the trim, the base price and the Massachusetts add-ons can test a loan or lease against a full figure, not a starting number. Owning the car matters after the sale too. In a January 2026 Google review, Todd M. wrote: “Quick service, great loaner vehicle, professional staff”
