What does a Mercedes-Benz S-Class cost for Westwood buyers?

The S-Class price a Westwood buyer sees is where the number starts. Massachusetts tax, title and document charges sit on top of the sticker, and the financing route you choose changes the monthly figure. Mercedes-Benz of Westwood prices every S-Class upfront, in one store with new and pre-owned cars, financing, leasing and a service department.

How much is a new S-Class once a Westwood buyer adds fees and tax?

At Mercedes-Benz of Westwood, we price every S-Class upfront, so the full number is in front of you before you visit. The Massachusetts charges that sit on top of the sticker are predictable, and you can add them before you sit down. The Massachusetts Department of Revenue (2022) sets the sales tax on a vehicle bought from a registered dealer at 6.25%. Massachusetts Department of Revenue Directive 14-1 (2014) treats a dealer’s separately stated document preparation fee as part of the sales price, so the same tax applies to that fee. The directive also keeps fees paid to the RMV out of the document fee, which means the state’s own charges appear as separate lines. The Massachusetts Registry of Motor Vehicles (2025) charges $75.00 for a certificate of title, and that line belongs on the paperwork you compare.

What does each 2027 S-Class trim cost and include?

The S-Class trims with EPA certification for the 2026 model year are the S 500 4MATIC® and the S 580 4MATIC®. Both are hybrids with all-wheel drive and a nine-speed automatic. The S 500 has a 3.0-liter six-cylinder engine, and the S 580 has a 4.0-liter eight-cylinder. The EPA lists the S 500 at 20 mpg city, 29 mpg highway and 23 mpg combined, with a fuel cost of $3,350 a year. The EPA lists the S 580 at 17 mpg city, 27 mpg highway and 20 mpg combined, with a fuel cost of $3,900 a year. On those EPA numbers, the S 500 has the lower fuel line, so a buyer who drives a lot should weigh that gap when choosing a trim. For the 2027 model year, Mercedes-Benz lists the S 500 4MATIC® Sedan from $112,550 and the S 580 4MATIC® Sedan from $134,600.

What do pre-owned and certified S-Class models cost near Westwood?

A vehicle bought from a registered dealer in Massachusetts carries the 6.25% sales tax, according to the Massachusetts Department of Revenue, and the title and document lines from the first section apply as well. The price depends on the specific car, its trim and its mileage, so a pre-owned buyer should compare each car on its own numbers. Start with the car you want to see, then add the tax and title lines to its listed price.

Should a Westwood buyer finance, lease or pay cash for an S-Class?

We offer new Mercedes-Benz financing, pre-owned car loans and Mercedes-Benz leases, so the route you choose is yours to make. The monthly figure matters most on a flagship sedan. Edmunds reports that a record 19.3% of consumers who financed a new vehicle in Q2 2025 committed to a monthly payment of $1,000 or more, a national figure that shows how large the financed amount can grow. Knowing your payment before you visit lets you compare the loan and the lease on the same S-Class.

How much will Mercedes-Benz of Westwood pay for your S-Class trade-in?

A trade-in lowers the price of the next S-Class, though Edmunds reports that 28.2% of trade-ins in July 2025 involved negative equity. Our Sell Your Vehicle tool gives a price online from a license plate and state, with VIN and make and model as other inputs. We also offer to buy a customer’s leased vehicle. Before you trade, know what you owe. Edmunds also reports that those buyers owed an average of $6,902 above the vehicle’s value. If your loan balance is higher than the car’s value, that gap has to be covered in the deal.

Frequently asked questions

Does the S-Class price include destination and Massachusetts sales tax?

The Massachusetts sales tax and the title and document lines belong in the total you compare. The maker’s destination charge is a separate line from the trim price, so check that line on the trim you choose. Our store advertises upfront pricing, so the number you see should show each line clearly.

Can I get approved for S-Class financing online before I visit?

You can start online with our secure finance application. Once you have a loan payment, compare it against the lease on the same car in the showroom.

How can I compare quotes on the same S-Class trim?

Ask for the full price on the same trim, with the tax, title and document lines shown. We advertise upfront pricing, so the number you see is the number to test against those lines. Compare the monthly figure only after you know the total.

Can I schedule an S-Class test drive online?

You can schedule a test drive online by scanning a QR code and uploading your driver’s license.

Can I finance a pre-owned S-Class?

We offer pre-owned car loans alongside new Mercedes-Benz financing and leases. Ask for the loan terms on the specific car, since the payment depends on its price and your credit.

Can I request parts for my S-Class online?

You can request parts through an online form, and we tell you when the parts arrive. The form is a request, not an online checkout.
