What should you decide before shopping for an S-Class in Westwood?
Decide four things before you visit: new or pre-owned, the body style (sedan, coupe, cabriolet or Maybach), the trim and powertrain, and your budget. We sell new S-Class models, including the S-Class Coupe and S-Class Cabriolet, so the body style and trim are the first choices to settle.
On trim, the choice starts with two S-Class sedans. The S 500 4MATIC® Sedan is $112,550, and the S 580 4MATIC® Sedan is $134,600, both as 2026 model year starting MSRPs.
What do the current Mercedes-Benz S-Class trims cost and include?
The 2026 S 500 4MATIC® Sedan starts at $112,550 with 442 horsepower and 413 lb-ft of torque. The 2026 S 580 4MATIC® Sedan starts at $134,600 with 530 horsepower and 533 lb-ft of torque.
Both are hybrids. The EPA certifies the S 500 at 23 mpg combined and the S 580 at 20 mpg combined. If you want more power, the S 580 is the trim. If you want the lower starting price and the better combined mileage, the S 500 is the trim.
How do you find an S-Class with upfront pricing at Mercedes-Benz of Westwood?
Start with the S-Class model you want from our new inventory, including the S-Class Coupe and S-Class Cabriolet. Then check the full price before you agree to anything.
Our How it Works page says, “Before you make any commitment, we’ll send you a purchase summary outlining every aspect of your purchase, including cash, finance, and lease alternatives.” That summary is the point to compare the cash, finance and lease numbers side by side.
Our process also includes an online deal sheet. On our C-Class sedan page, we say, “You’ll be presented with a fully transparent online deal sheet that includes the price of the car and all associated fees.” Read the fees on that sheet before you visit.
How do you value your trade at Mercedes-Benz of Westwood online?
You can value your trade online from your license plate. On our trade-in page, we say, “Enter your license plate number and select the state it’s registered in, then click ‘Get My Price’ to see your trade-in offer.”
If you would rather use the VIN, the same page says, “Enter your VIN (visible from outside the car on the driver-side dash or on the driver’s door jamb), then click ‘Get My Price’ for an instant offer.” Sell My Car Online asks for three things: your VIN, a few questions about the car, and vehicle photos (Mercedes-Benz of Westwood).
How do you apply to finance or lease an S-Class in Westwood?
We offer new Mercedes-Benz financing, pre-owned car loans, and Mercedes-Benz leases, so you can compare a lease and a loan before you choose. Our online application says, “Complete our 2 step credit form in minutes, your personal data will be protected with secure two factor authentication.”
Gather your documents first. Our How it Works page says, “We’ll need you to complete a credit application and upload a copy of your driver’s license and a valid insurance card.” It adds, “Even for cash buyers, we need to collect a short form (federal requirement).”
A lease is taxed in Massachusetts as a retail sale unless it is for resale in the regular course of business (Legal Information Institute, 830 CMR § 64H.25.1). A lease does not avoid the state’s sales tax.
How do you book an S-Class test drive in Westwood?
You can book a test drive online by scanning a QR code and uploading your driver’s license. We are at 425 Providence Hwy, Westwood, MA 02090.
Our sales hours run Monday to Thursday from 9:00 AM to 7:00 PM, and Friday to Saturday, opening at the same hour and closing at 6:00 PM. Sales are closed on Sunday. Bring the trim you picked earlier so the drive covers the car you plan to buy.

We offer a state-of-the-art service center. Our service center page says, “We also offer a Lyft station, loaner vehicles, pick-up & delivery service, state inspections and free vehicle appraisals.”
Ask about the loaner before your service visit so you can plan the day around it.
FAQ
What taxes and fees apply when you buy an S-Class in Massachusetts?
A vehicle bought from a registered Massachusetts dealer carries a 6.25% sales tax (Massachusetts Department of Revenue, 2022). A dealer’s separately stated document preparation fee is taxed as part of the sales price (Massachusetts Department of Revenue, Directive 14-1, 2014). The Massachusetts Registry of Motor Vehicles charges $75.00 for a certificate of title (Massachusetts RMV, 2025).
What should an S-Class price quote show before you sign?
Massachusetts requires a dealer’s advertised price to include charges that are usual before delivery, such as documentary preparation, but not taxes or optional title and registration help (Legal Information Institute, 940 CMR § 5.02). If a price leaves out standard equipment, the advertisement must say so clearly (Legal Information Institute, 940 CMR § 5.02). Ask for a quote that lists the tax and the title and registration lines separately.
What is the difference between an S-Class and a Maybach S-Class?
Choose the Maybach when rear-seat space comes first, and a standard S-Class when price is the bigger concern.
What warranty comes with a new S-Class?
The 2026 S-Class carries a basic warranty of 4 years or 50,000 miles, according to Mercedes-Benz’s published 2026 warranty and service booklet. Read that booklet for the exact terms before you buy. Ask us which warranty applies to the car you are buying.
