An Austin AMG® SL costs more at each step from SL 43 to SL 63

The SL 43 is the lowest-priced SL-Class trim, and each step up to the SL 55 and then the SL 63 carries a higher starting price. Mercedes-Benz publishes all three as 2026 model-year starting prices.

Start with the SL 43 when you set a budget, because it is the floor of the range. The SL 55 and SL 63 cost more to buy. The next sections show what that extra money buys and what the tax and fees add on top.

What do you get for the extra money from SL 43 to SL 63?

The extra money buys engine output. The SL 43 makes 416 horsepower and 369 lb-ft of torque. The SL 55 makes 469 horsepower and 516 lb-ft, and the SL 63 makes 577 horsepower and 590 lb-ft, according to Mercedes-Benz’s 2026 specifications.

Interior room does not change across the three. Legroom in row one is 41.5 inches and maximum cargo is 7.5 cubic feet on the SL 43, SL 55 and SL 63 alike. If you want space more than power, the SL 43 gives you the same room for less.

Compare the power figures against how you plan to drive the car before you pick a trim.

What tax and fees does an Austin buyer add to an SL price?

Texas charges motor vehicle sales tax of 6.25% on the sales price, minus any trade-in allowance (Texas Comptroller of Public Accounts, 2026). Title and registration fees come on top of that at purchase.

The title fee is $33 in Travis County, where Austin sits (Texas Department of Motor Vehicles title manual, 2026). The standard registration fee for a car is a $50.75 base fee plus $1 for the TexasSure program, shown as $51.75 on a renewal notice (Texas Department of Motor Vehicles, 2026). The local county fee on the TxDMV fee chart is $11.50 in Travis County (Texas Department of Motor Vehicles fee chart, 2026).

Every figure in this example is hypothetical. Say, hypothetically, a buyer takes the SL 43 at $112,550 with no trade-in. At 6.25%, the sales tax comes to $7,034.38, before the title, registration and county fees.

What financing and leasing offers cover a new SL in Austin?

At Mercedes-Benz of South Austin, we offer both financing specials and leasing specials. The specials are set on the store’s own terms, so ask which one applies to the SL trim you pick before you sign.

Run both routes on the starting price of the trim you want, plus Texas tax and fees. Then compare the monthly payment on each route against the total you will pay over the term.

How does a trade-in lower what you pay for an SL in Austin?

Texas taxes the SL’s price after the trade-in allowance comes off, so a trade-in lowers the amount the tax applies to. How much the store offers for your car is a question to put to us directly.

Every figure in this example is hypothetical. Say a buyer trades in a car for $20,000 toward the SL 55 at $145,250. The taxable price falls to $125,250, and at 6.25% the sales tax is $7,828.13.

They offered a fair trade-in value and a competitive sales price. Super clean showroom and vehicles. Super nice/helpful staff who did not pressure us. Easy to buy a vehicle from them, and feel good about the deal!” Darren J. described the trade-in value as fair.

FAQ

What is the destination charge on a new Mercedes-AMG® SL?

Mercedes-Benz’s 2026 SL-Class guide says its pricing excludes a $1,350 destination and delivery charge (Mercedes-Benz USA quick reference guide, 2026). Budget for that charge on top of the starting price.

How do options change the final price of an AMG® SL?

Prices here are starting MSRPs, and each option you add raises the total. Texas taxes the sales price, so each option also adds to the sales tax.

Does a new SL come with a warranty?

Yes. Mercedes-Benz lists a basic warranty of 4 years or 50,000 miles on the SL-Class (Mercedes-Benz warranty and service booklet, 2026).

What fuel economy does the EPA list for the SL 43, SL 55 and SL 63?

For the 2026 model year, the EPA certifies the SL 43 at 19 mpg city, 27 mpg highway and 22 mpg combined.

How does the SL’s price compare with the CLE Cabriolet and AMG® GT?

Within our lineup, the CLE 300 4MATIC® Cabriolet starts at $69,400 and the AMG® CLE 53 Cabriolet starts at $85,700. Both start below the SL 43.

Which model year do the published SL prices apply to?

Mercedes-Benz lists the starting prices for the 2026 model year below. Check the model year on any listing you compare against them.
